Rationalizing a denominator - free math help on homework, 5root(5) / 2root(10)

The video tutorial explains how to simplify a rational expression involving square roots. The instructor begins by addressing the need to eliminate the square root of 10 from the denominator by multiplying both the numerator and denominator by it. The process involves multiplying terms and applying the rule of exponents to combine square roots. The instructor then demonstrates how to simplify the resulting expression further by reducing square root 50 to 5 times square root 2, ultimately arriving at the final simplified form of the expression.
