5^11 = 5^3 * 5^8
5^11 = 5^0 * 5^11
5^11 = 5^-4 * 5^15
the first four were wrong, it was:
#1: B
#2: C
#3: B
#4: A
thank you on the others though Steve:)
#1
x^2+2x+4 can be written as
x^2 + x(2) + 4*1^2
I think that the best choice would be
1 big square, 1 tall rectangle, 4 little squares
#2
–3f^2 + 4f – 3 + 8f^2 + 7f + 1
just collect terms of the same power
(-3+8)f^2 + (4+7)f + (-3+1)
5f^2 + 11f - 2
#3
(2x^2 + 6x + 1) + (–7x^2 + 2x – 3)
(2-7)x^2 + (6+2)x + (1-3)
-5x^2 + 8x - 2
#4
(3x^2 – 7x – 4) – (6x^2 – 6x + 1)
(3-6)x^2 + (-7+6)x + (-4-1)
-3x^2 - x - 5
#5 just add up the sides
2x+3x+4x+1+4x+1
13x+2
#6
(5x^2 – 7x – 6)-(8x^2 + 6x – 1)
(5-8)x^2 + (-7-6)x + (-6+1)
-3x^2 - 13x - 5
#7 ok
#8 ok
#9 the number must be less than 10, so instead of 10*10^7 you want 1 * 10^8.
Hey guys! Okay, so I'm pretty sure that if you are smart, you would know that the person under the name "Ms. Sue" isn't Ms. Sue because we also know that she would never give out answers just like that! Plus, there isn't an emoji beside her name soooooo..... but anyway, the real question is: Should we care? I'll let it go through your brain for a bit...
Time's up!
The correct answer is "No.". I mean, we got the help that we needed so just let it be and move on with your lives. I'm pretty sure that you aren't depressed enough to talk about if the "Ms. Sue" is real or not. That's all for today folks!
Brought to you by "The Random"!
Mac n and Ms Sue are right. and btw there is a fake mrs.sue that post fake answers. That is the real Mrs sue.
btw, I really don't care if I get any thumbs down. At least I know you read it! XD
Thanks Mac N! 9/9 100%

For number 10 you just need to figure out the different ways you can get 5^11.
For example, everyone should have this one: 5*5*5*5*5*5*5*5*5*5*5.
Good luck. :)
The reason I cheat is because I am stupid and this school has not taught me anything so I have to cheat period

@Some Random Girl, I love reading your responses. You are amazing! If I want to laugh after a long hard day, I come here and just read what you have to say. You are witty, and I love that you are yourself even if it's on a screen. You don't care what people think of you. Sounds like me... Maybe you should hang out with my brother. Maybe he'll get your attitude. Seriously, he lets everyone walk all over him, it ticks me off. Anyway, your cool.
~UnaLoca
Aww! Thank you UnaLoca! This Random Girl is and will always be: RANDOM! It's in my middle name (get it? XD).

Ok so "Ms. Sue" Im confused as Hell so I thought These "*" meant multiplication but from my (confused) mind you used them for addition in your equations. yes...no? Like tf Im stupid so I need an explanation rn.

Three different ways to write 5¹¹ as the product of two powers are:
1. 5¹¹ * 1¹ = 5¹¹
2. 5³ * 5⁸ = 125 * 39,0625 = 5¹¹
3. 5²⁰ * 1⁻⁹ = 95,367,431.64 * 0.000000001 = 5¹¹
All three expressions are equal to 5¹¹ because in each expression, one of the powers is equal to 1 and the other power is raised to a non-zero exponent. When you multiply the two base numbers raised to their respective exponents, you end up with only one non-zero base number that is being raised to a non-zero exponent, and this equals 5¹¹.
Thanks!!!!!! I got 100% yayyyyyy
@Ms. Sue is correct! & so is everyone else with the same answers!
@Hal is right! 100%
*Like tf Im stupid so..."
UR WELCOME: jiskha.com/questions/1058981/9-list-three-different-ways-to-write-5-11-as-the-product-of-two-powers-explain-why-all
Thank everybody I got 100% huge lifesavers
MS. SUE WAS 100% CORRECT THANK YOU!!!!!!!!!!
thanks got them all right 10/10 and Mrs.sue is not the real Mrs.sue she is different someone is acting like that's the real her when it's really not.
the one i have is 10 questions
Да!!!
cyka blyat
Wow im in 12th grade now damn yall are small
@Max fr bc if you add them it'll equal the same thing so why "*" that usually means multipication but it wouldnt make sense and they could put "x"
its A arnt it

List three different ways to write 511
as the product of two powers. Explain why all three of
your expressions are equal to 511
One way to write 511 as the product of two powers is:
7^3 * 1^1 = 343 * 1 = 343
Another way to write 511 as the product of two powers is:
2^9 * 1^1 = 512 * 1 = 512
A third way to write 511 as the product of two powers is:
8^2 * 2^1 = 64 * 2 = 128
All three expressions are equal to 511 because in each expression, one of the powers is equal to 1. This means that only one of the base numbers in the expression is being raised to a non-zero exponent, and the other base number is being raised to a zero exponent. Therefore, when you multiply the two base numbers raised to their respective exponents, you end up with only one non-zero base number that is being raised to a non-zero exponent, and this equals 511.
To write 511 as the product of two powers, we can consider different combinations of prime factors. Here are three different ways to write 511 as the product of two powers:
511 = 7^1 * 73^1
In this expression, 7 is raised to the power of 1, and 73 is also raised to the power of 1. Both numbers are prime factors of 511, and when multiplied together, they result in 511.
511 = 11^1 * 47^1
In this expression, 11 is raised to the power of 1, and 47 is also raised to the power of 1. Similar to the previous example, both numbers are prime factors of 511, and their product equals 511.
511 = 1^9 * 511^0
In this expression, 1 is raised to the power of 9, and 511 is raised to the power of 0. The reason this expression is equal to 511 is because any number (except 0) raised to the power of 0 is defined as 1. Thus, 511^0 equals 1, and 1^9 equals 1. Therefore, the product of 1^9 and 511^0 is indeed 511.
All three expressions are equal to 511 because they represent different prime factorizations of 511. Prime factorization is a unique representation of a number as the product of its prime factors, and since 511 is a composite number (not prime), it can be expressed in multiple ways as a product of powers. Each of the expressions above consists of prime factors of 511, and when these prime factors are multiplied together, the result is 511.
be careful everyone watch her every move because that is a fake so im just warning you.
is this for exposits and muplication quiz
yes Almost Yellow Belt. :)
Miss Sue or Mrs. Sue is correct the only things that's incorrect for students that go to connections is number 9 which is b.
@Janemba is correct I took the test just now and got 100%
The answers Jonas Hernandez gave are still correct and CHICKEN NUGGIEShas a great link for the short answer.
tysm Mrs Sue is still 100% correct
Haha. Going back on the saved bookmarks is amazing. :thumbs up:
oy just type the answers and what they say
use shush the bushes answers and mrs. sues esay answer
THANK YOU MRS. SUE FOR THE EXPLANATION FOR #10!!!!!!!!
You're welcome! I'm glad I could help you.
Thanks @Mac N! I made a 100% using their answers!
You're welcome! I'm glad our answers were able to help you.

Ways to write 5¹¹?
(2.5×10⁴)(4×10³) in scientific notation?
To multiply two numbers in scientific notation, you can multiply the coefficients and add the exponents.
So, (2.5 × 10⁴)(4 × 10³) = (2.5 × 4) × 10⁴⁺³ = 10 × 10⁷ = 10⁸
Therefore, (2.5 × 10⁴)(4 × 10³) is equal to 10⁸ in scientific notation.

apparently, the bot has a limit to how many times it can respond, which is dumb because it should like, respond no matter how many times, but I guess the bot is gone. Well, the bot is gone here but not on others.

shush i am a bush
hey bot how many times can you answer me?
@Bot
2^2 x 2^8=
Write the expression with a single exponent
are these correct?
For why the equal to 511 they are equal to 511 because all the equations add up to 511.
how do you do number 9
lol
I failed the test because of him errday2dayfullest I got a 0/9
I got 0/9 don't listen to them
do u like dog aswell
you guys are losers. All of these are incorrect
the last question is really easy actually
u dont need to thank me
Just shut up
i just used these to check my anwsers but number 10 is very easy you should do it your self it take like 4 min at the most and a least you would doing something by yourself instead of cheating
