Answer 1

Let's go over each of the expressions and see if they are equal to 1/8

`2^(-3)=(1)/(2^3)=(1)/(8)`

So A is equivalent

`(-8)^1=-8`

So B is not equivalent

`((32)/(4))^(-1)=(1)/((32)/(4))=(4)/(32)=(1)/(8)`

So C is equivalent

`8^8-8^9=-117440512`

So D is not equivalent

`(8^8)/(8^9)=8^(8-9)=8^(-1)=(1)/(8)`

So E is equivalent
