This may have been discussed somewhere before, but anyway....
On the HP 50g if you find the cube root of 15 (in RPN mode, not that it matters)
15^(1/3)
I get the traditional "cube root of 15". However if I do the cube root of 16, out pops:
e^(4ln(2)/3), which is of course correct, but not the traditional "2 times the cube root of 2".
If I find the cube root of 2, and then multiply by 2, it stays "2 times the cube root of 2", not the previous exponential equivalent.
Question: is there any way to avoid the exponential form, or avaluate or convert it to the traditional form? This is perplexing me.
Also, when you cube the result, the exponential form stays complicated, while the traditional form reverts back to 16.
Thanks.
