    Hello, andyboy179!

    I assume you are just learning about exponents.


    I have: . 5^3,\:(\text{-}3)^2,\:(\text{-}2)^3

    i think the first one = 125 but im not sure. . Right!
    any help will be helpful

    5^3 \:=\:(5)(5)(5) \:=\:125

    (\text{-}3)^2 \:=\:(\text{-}3)(\text{-}3) \:=\:9

    (\text{-}2)^3 \:=\:(\text{-}2)(\text{-}2)(\text{-}2) \:=\:-8
