Question

Help me plzzzzzz!!!!

Answer 1

5^-3 = 1/125
-5^-3 = -1/125
(-5^-3)^-1 = -125
(-5^-3)^0 = 1

Answer 2

5⁻³ =
`(1)/(5^(3) )` =
`(1)/(5*5*5)` =
`(1)/(125)`

-5⁻³ = -
`((1)/(5^(3) ))` = -
`((1)/(5*5*5))` =
`(-1)/(125)`

(-5⁻³)⁻¹ =
`(1)/(-5^(-3) )` = -(5³) = -(5*5*5) = -125

(-5⁻³)⁰ = 1 (anything to the zero power equals 1, except 0⁰ = 0)
