Question

If a = 6, which of the following is equal to a 2?1o-36O O-122

Answer 1

The question given is a negative exponent.

To solve this, we apply the law of indices for negative exponents.

Negative exponent law is indicated below;

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

Thus, applying this law to the question;

`a^(-2)=(1)/(a^2)`

Given:

a = 6

Substituting a = 6 into the expression, we have;

`(1)/(a^2)=(1)/(6^2)`

Therefore, the correct answer is;

`(1)/(6^2)`
