Your welcome 🙏
Have a great day
then wat is 3
Nobody is correct for me! Tysm!
no idea. Reread the problems. I figure you have mixed up #3 and #4, since the numbers are totally different.
to get your own answer, just move the decimal place 4 spots to the right:
6.8x10^0 = 6.8
6.8x10^-1 = 0.68
6.8x10^-2 = 0.068
. . .
in scientific notation, the leading value n is always 1.0 <= n < 10.0
2b
3? no relation between 6.8 and choices
5c
whats the answer
Sure, I'd be happy to help! Let's break down each question step by step to find the correct answers.
2. To represent the number 0.00000916 in scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10, and then multiply it by the appropriate power of 10.
Starting with 0.00000916, we can move the decimal point 6 places to the right to get 0.00916. This gives us a number between 1 and 10.
Now, the decimal point needs to be moved 6 places to the left to match the original number. This means the power of 10 will be negative.
Therefore, the number 0.00000916 in scientific notation is represented as b. 9.16 x 10^-6.
3. To convert the number 6.8 x 10^-4 into standard form, we need to follow the reverse process.
Starting with 6.8 x 10^-4, we move the decimal point 4 places to the right to get 0.00068.
Now, the number is in standard form.
Therefore, the number 6.8 x 10^-4 in standard form is represented as c. 0.00000000575.
5. To convert the number 5.2 x 10^8 into standard form, we follow a similar process as above.
Starting with 5.2 x 10^8, we move the decimal point 8 places to the right to get 520,000,000.
Now, the number is in standard form.
Therefore, the number 5.2 x 10^8 in standard form is represented as c. 520,000,000.
I hope this helps! If you have any more questions, feel free to ask.
