Find the root. Assume that all variables represent nonnegative real numbers. \( \sqrt[5]{x^{30}} \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The root is not a real number. B.

We begin with the expression \[ \sqrt[5]{x^{30}}. \] Recall that taking the fifth root of a number is equivalent to raising it to the power of \( \frac{1}{5} \). Thus, we have \[ \sqrt[5]{x^{30}} = \left( x^{30} \right)^{\frac{1}{5}}. \] By using the exponent rule \(\left(a^m\right)^n = a^{mn}\), we get: \[ \left( x^{30} \right)^{\frac{1}{5}} = x^{30 \times \frac{1}{5}} = x^6. \] Since \(x\) is assumed to be a nonnegative real number, the expression \(x^6\) is also a nonnegative real number. Thus, the correct choice is (if option B indicates \(x^6\)): \[ \boxed{x^6}. \]
