The cube root is just a fractional exponent in disguise. When you see a radical like $\sqrt[3]{7}$, remember that the index (the small number 3) becomes the denominator of the exponent, and the radicand (7) stays as the base. This connection between radicals and exponents lets you rewrite any root as a power.
