Rewrite the radical expression as an expression with a rational exponent.

Question

the seventh root of x to the thrid power

a x to the three sevenths power
b x to the seven thirds power
c x21
d x4

Answer 1

The expression for the seventh root of \( x^3 \) can be rewritten using a rational exponent as follows:

\[ \sqrt[7]{x^3} = x^{3/7} \]

So the correct answer is:

a. \( x^{\frac{3}{7}} \)
