Answer:
Subtract the "x" exponents and the "y" exponents vertically. Then add the exponents horizontally if they have the same base (subtract the "x" and subtract the "y" ones). Finally move the negative exponent to the denominator.
How to simplify:
if you are going to simplify a radical expression, it can be written by using rational exponents.
Rational exponent is an exponent that can be expressed as m/n , where m and n are integers and n ≠ 0.
