Example Question #71 : Understanding Radicals

Rewrite the following radical as an exponent:

Possible Answers:

Correct answer:

Explanation:

In order to rewrite a radical as an exponent, the number in the radical that indicates the root, gets written as a fractional exponent. Distribute the exponent to both terms by multiplying it by the exponents of each term as shown below:

From this point simplify the exponents accordingly:
