Question: How can I get more "clean" radical answers when normalizing an integral expression for Quantum Mechanics?

I'm trying to solve a Quantum Mechanics problem that requires me to normalize a wavefunction before I proceed. I have the book solutions to these problems (I'm just trying to practice solving using Maple) so I know what the answers are SUPPOSED to be. But I'm not getting the answers I expected when dumping it into Maple.

What I put into Maple:

What I was SUPPOSED to get:

I assume this is a radical simplication I need to make. But in highlighting the expression, right clicking, and trying the different simplification options, nothing worked.

Thanks!
