If x is positive, p and q are integers where q is positive then,
x^(p/q)= q root of (x^p).
So (81/16)^(3/4) = 4 root of [ (81/16)^(3) ] = 27/8 or 3 3/8.
Can someone please help me solve
Hopefully this displays correctly. In case it doesn't here it is again:
(81 / 16)^(3 / 4)
I can solve it with the calculator obviously (3 3/8), but I need to demonstrate it and I can't figure out how.
Thank you so much for your help!
