Question

Simplify (3x^2 y)^-3

Answer 1

`image`

Answer 2

we are given

`(3x^2 y)^(-3)`

firstly , we can make exponent positive

`(1)/((3x^2y)^3)`

now, we can distribute exponent

`(1)/((3x^2)^3(y)^3)`

`(1)/((3)^3(x^2)^3(y)^3)`

we can combine exponents

and we get

`(1)/(27x^6y^3)`...........Answer
