$u^3=-5$
Learn how to solve equations problems step by step online. Find the roots of u^3=-5. Find the roots of the equation using the Quadratic Formula. Removing the variable's exponent raising both sides of the equation to the power of \frac{1}{3}. Divide 1 by 3. Simplify \sqrt[3]{u^3} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 3 and n equals \frac{1}{3}.
