what expression raised to the forth power is 81x^12y^8z^16?
:
Wouldn't it be: %2881x%5E12%2Ay%5E8%2Az%5E16%29%5E%281%2F4%29?
:
Using the rules of exponents:
:
81%5E%281%2F4%29 = 3
%28x%5E12%29%5E%281%2F4%29 = x%5E3
%28y%5E8%29%5E%281%2F4%29 = y%5E2
%28z%5E16%29%5E%281%2F4%29 = z%5E4
:
So you have: %283x%5E3%2Ay%5E2%2Az%5E4%29
:
Check: %283x%5E3%2Ay%5E2%2Az%5E4%29%5E4 = 81x%5E12%2Ay%5E8%2Az%5E16
