Question

Please help.
(2^3)^-8
Answer using exponential notation with positive exponents.

Answer 1

1 / 8^8

Answer 2

Can you explain how you reached your answer please?

Answer 3

2^3 = 2*2*2 = 8

Answer 4

then , 8^-8 means 1 / 8^8

Answer 5

as an example , 1^-3 would mean 1 / 1^3

Answer 6

Remember this as a rule

Answer 7

Wouldn't you multiply the number by itself the number of times of the exponent to clear it?

Answer 8

Do you want to remove the exponent ?

Answer 9

If you want to remove the exponent then yes, that is what you would do

Answer 10

I don't think so, but this stuff confuses me so much that I just don't know. The question in my text is written just as I wrote it here, so I believe it's mainly just asking for simplification, not solving. So, I'm guessing that, no, I don't need to clear the exponents. What is the rule I should remember?

Answer 11

The rule that you should remember in such a question where you are required to give your answer in positive exponent is that , if for exampe you are given 1^-3 , that equals 1 / 1^3 .It's as simple as that

Answer 12

When you divide it by 1 , the sign of your exponent changes. When you divided 1^-3 by 1 , the sign of your exponent changed , hence your answer would be 1 / 1^3

Answer 13

Ok. :Thank you so much. I think I understand a little better now. :)
