Just need someone to check my answer to this
-(4)^-2

my answer is -1/4^2

Answer 1

right. but i think you should simplify that denominator

Answer 2

so just -1/2^2

Answer 3

simplifying the denominator means calculating the value of 4^2
u know what 4^2 equals?? or what is the square of 4?

Answer 4

4^2=16

yes! so finally the simplified answer will be -1/16 ....isn't it?

Answer 7

Answer 8

if \(-\frac{1}{4^2}\) is in the choices then just stick with that

Answer 9
