Your use of parenthsis is causing confusion.

2³ = 8
3³ = 27

Are you looking for (⅔)² = 4/9

Or is the cube root portion just the 8?
(2 / 27)² = 4/729.

If x³ = 8/27
take the cube root of the fraction to get
x = 2/3.
Then (2/3)² = 4/9.
I hope I've interpreted this correctly.

take the cube root of 8 which is 2
then take the cube root of 27 which is 3
so now u have 2/3 to the second or squared
2/3 times 2/3 = 4/9
4/9 is ur answer

cube root (8/27)= 2/3

squared: (2/3)^2= 4/9

4/9 = [(Cube root of 8/cube root of 27) X (Cube root of 8/cube root of 27)].

((8/27)^(1/3))^2

let us consider like this,

[8^(1/3)]/[27^(1/3)]

(2^3= 8 & 3^3= 27)

=> [(2^3)^(1/3)] / [(3^3) ^ (1/3)]

(cuberoot & cube cancels)

=> 2/3

but the question is,

[8^(1/3)]/[27^(1/3)]^2

=> (2/3)^2

=> 4/9

did u get ur answer?

first square both
(8^2/27^2)^1/3
(8^2/3)/(27^2/3)
4/9
