Answer:

#x=+-27#

Explanation:

Given:

#x^(2/3)+15 = 24#

Subtract #15# from both sides to get:

#x^(2/3) = 9#

Cube both sides to get:

#x^2 = 729#

Take the square root of both sides, allowing for both positive and negative square roots to get:

#x = +-27#

Assuming that we are dealing purely with Real numbers, both of these solutions are solutions of the original equation.
