HP 50G - Simplifying Radicals

[maxlockett619]

Hey everyone! Just picked up a 50G off eBay after my Prime's LCD cracked, and so far I really like the calculator. The one thing that I can't figure out is how to correctly simplify radicals on this calc. On the Prime, inputting an expression such as:


Would return x^(4/3). This is the value that I need. On the 50g, simplifying the expression gives me a bunch of natural logs and e values. Is there any way to make the 50g behave like the Prime in that respect.

Figured I should add, in my CAS settings, the only things that I have checked are Incr Pow and Rigorous.
