Consider the following two cases for any real number Because our radical has an even index and the variables have even exponents, we will need to use absolute value symbols to simplify our expression.
Now, considering that is an even number, we can simplify the obtained expression. Finally, since the exponent of the numerator is even, it is always positive. Moreover, is also a positive number. This means we can remove the absolute value symbol from the numerator and from
