Solve for x over the real numbers:
$4 \sqrt{x^{3} - 7} = 0$

Divide both sides by a constant to simplify the equation.
Divide both sides by 4:
$\sqrt{x^{3} - 7} = 0$

Hint: Eliminate the exponent.
Square both sides:
$x^{3} - 7 = 0$

Hint: Isolate terms with x to the left hand side.
Add 7 to both sides:
$x^{3} = 7$

Hint: | Elminate the power on the left hand side.
Take cube roots of both sides:
Answer: $x = 7^{\frac{1}{3}}$
