Question

I need help. Someone please figure it out

Answer 1

`(1)/(2^(n) )`

Explanation:

The rules of exponents state that

`a^(-m)` =
`(1)/(a^(m) )` and
`a^(0)` = 1

Thus

`2^(-5)` =
`(1)/(2^(5) )` =
`(1)/(32)`

`2^(-4)` =
`(1)/(2^(4) )` =
`(1)/(16)`

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

and so on , to

`2^(0)` = 1
