The two expressions are NOT equivalent!

It would be the fourth root of b!!

 

The command you are looking for is "combine":

Don't use "simplify" after combine!

In general, the possibilities to affect and control the output of symbolic simplifications in Prime are very limited compared to other programs. Even Matlab, which also uses muPad for symbolic calculations, offers much more options.
