Learn how to rationalize the denominator of an expression with a radical on denominator

The video tutorial explains how to simplify expressions with radicals in the denominator. It begins by discussing the need to eliminate radicals from the denominator and introduces the concept of square numbers, which are numbers multiplied by themselves. The tutorial then explains the correct method to multiply radicals, emphasizing that numbers outside the radical cannot be directly multiplied with numbers inside the radical. Instead, the same radical must be used to multiply both inside and outside numbers to simplify the expression.
