(x+4)^(2/3) = 9

To do this, we raise both side by 3/2, so that the exponent 2/3 of the term on the left side will be cancelled:

(x + 4)^(2/3 * 3/2) = 9^(3/2)

(x + 4)^(1) = 3^3

x + 4 = 27

x = 27 - 4

x = 23

To check, substitute the x value to the original equation:

(23 + 4)^(2/3) = 9

27^(2/3) = 9

3^2 = 9

9 = 9

Thus x is indeed equal to 23.

Hope this helps~ :3
