This is the currently selected item. Were asked to divide and simplify and we have one radical expression over another radical expression the key to simplify this is to realize if I have the square the principal root of x over the principal root of y this is the same thing as the principal root of x over Y and it really just comes out of the exponent properties if I have two things but I take to some power and picking the principal root is the. Click the blue arrow to submit and see the result.

In this second case the numerator is a square root and the denominator is a fourth root. Divide rational expressions step-by-step. If n is even and a 0 b 0 then.
