Question

I have an exponent properties test tomorrow, its our last one before the final, so its important, but anyways, there is one question on the review that is confusing me. Could you please help? Here it is :

(2y2x7)(-xy)(9x-3y)

I don't know if the exponents showed up, but the numbers after x & y in the first parenthasis part are exponents, and the -3 on the last one is an exponent.
Sorry if this is confusing. Thanks! (:

Answer 1

I really need help with this, please!

Answer 2

Factor: (x^2-1)/(4x-12) X (3x^2-12+9)/(x^2+x)

Answer 3

are you multiplying this?

(2y^2 x^7) * (-xy) * (9x^-3 y)

If so the answer is,
-18x^5 y^4

Answer 4

@helper:

Yes, that's it! I wasn't sure how to type it.
I solved it while I was waiting, and that's the answer I got ,thanks so much!

Sure, I can help you with that! It seems like you have an expression with multiple terms, each having variables with different exponents. To simplify this expression, you can use the rules of exponent properties.

Let's take it step by step.

First, let's multiply the numbers outside the parentheses:
(2y^2x^7)(-xy)(9x^-3y)

Multiply the numbers: 2 * -1 * 9 = -18
Now, let's multiply the variables inside the parentheses:
y^2 * y = y^(2+1) = y^3
x^7 * x^-1 = x^(7-1) = x^6
x * x^-3 = x^(1-3) = x^-2

Combining all these results, we have:
-18y^3x^6x^-2

Now, let's simplify the exponents further:
y^3 is already simplified.
x^6 * x^-2 = x^(6-2) = x^4

Putting it all together, the simplified expression is:
-18y^3x^4

So, the simplified answer is -18y^3x^4.
