Default Rational Exponets:Alegbra II - 01-27-2012, 09:15 PM

So recently this past week my Algebra II class is learning about rationals/radicals. Today we're learning about Rational Exponets and it completly baffles me. Here is an example:
^=exponet *=multiply

m^3/4 * n^5/4

x^(m/n) = the n-th root of x to the power of m. So for example x^(1/2) = √x (that's supposed to be the square root symbol, hope it displays correctly).

Have you learned about regular exponents yet? When you have two bases to the same power, you can combine them together, same with rational exponent. So take what Elanorea said, and combine them to get: 4√(m^3*n^5). Plug all those numbers together and take the fourth root of that total.
