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

:confused: 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.
