Question

Evaluate the following expression.


(-6)^-2

Answer 1

1/36

Explanation:

`(-6)^(-2)` can be written as:

`(1)/((-6)^(2) )` (this is done by the law of indices
`a^(-m)=(1)/(a^(m) )` )

then by simplifying the above expression, we get:

`(1)/((-6 * -6)) =(1)/(36)`

So the final answer is 1/36 (
`(1)/(36)` )
