Question 141944: I am having difficulty trying to simplify radical equations that use exponents.
The problem I ma trying to solve is:
5x{sqrt(448x^5y^3}-3y{sqrt(63x^7y}
I understand I am supposed to factor down the 448 and 63, but I am not sure what is supposed to happen with the exponents. Any help is greatly appreciated.
