    Radicals and Exponents

    For these questions you are supposed to write an equivalent expression using exponents:

    (i don't know how to do this in computer talk so bear with me!!)
    the square root of the square root of x^4

    for this i thought the answer was:

    (x^\frac42)^\frac12

    the answer in the book is

    x

    ummm... how is the answer X????

    also...

    The cube root of the square root of x^6

    My answer:

    (x^\frac62)^\frac13

    Book:

    x

    Obviously i'm missing something.....

    Your answers are correct. What's the problem?. (4/2)(1/2)=1. That's right.
