EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS
Since the index of the radical is odd, there is no restrictions on the value of x in this problem.
Raise both sides of the equation to the power 3.
Subtract 15 from both sides of the equation
Multiply both sides of the equation by
The answer is x = -10.5
Check the solution by substituting -10.5 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
