Question

Which of the following is equal to the expression below

Answer 1

D

Explanation:

-6(2)=-12

5^-12

can't have negative power

1/5^12

Answer 2

Answer: OPTION D

Explanation:

We need to remember that, according to the Negative exponents rule:

`a^(-n)=(1)/(a^n)`

Then, we can rewrite the expression in the following form:

`(5^(-6))^2=((1)/(5^6))^2`

We also need to remember the Power of a power property, which states that:

`(a^n)^m=a^((nm))`

Then, applying this property, we get:

`(1)/(5^((6*2)))=(1)/(5^(12))`

This matches with the Option D
