What is three root 1/3 ? I'm not sure if that looks right in words, but I don't know how to post the square root symbol. If that doesn't make sense, then pretend that this sign: % is a square root:

3 %1/3

The 3 looks like it's a little above it. Please help me.
It's Radical Functions and Radical Exponents Ch.6, and I do not understand how to do this problem at all..
