2^frac(5)(3)

Explanation:

I'm wondering if you could call this a "simplification" but here it is "rewritten" in another form:
since 32=2*2*2*2*2=2^5,
we can write:
root(3)(32) =root(3)(2^5)=2^frac(5)(3)
(because root(3)(x) = x^frac(1)(3))
or if one absolutely wants to get some integer out of the root, we could write:
root(3)(32) =root(3)(8*4)=root(3)(2^3*4)=2root(3)(4)
