(3y(2/3))^-3

Answer 1

(3^(-3)y^(-2)) = 1/(27y^2)

Answer 2

this is what i got so tell me did i do it wrong

Answer 3

3^(-3) y^(-3 * 2/3) =

3^(-3) y^(-2) =

.1 . . .1 . . . . . . . 1
---- x ---- . = . ----------
3^3 . y^2 . . . . 3(3y)^2

Answer 4

that's correct btw

Answer 5

ok thank u so much
