Question

If a = 6, which of the following is equal to a -2?

-12
1/6^2
6^2
-36

Answer 1

The answer to the question is 1/6^2

Answer 2

1/6^2

Explanation:

Im assuming that you mean a to the power of negative to 2 with a being 6. 6 to the power of negative 2 is 0.027777 repeating, so it can't be -36 or -12. 6^2 is 36 so it can't be that either. 1/6^2 is 0.02777777 repeating so that is the answer. Ur welcome :)
