Learn to rationalize the denominator by simplifying the radical first

The video tutorial demonstrates how to simplify a rational expression with a radical by rationalizing the denominator. It begins by explaining the need to remove the square root from the denominator and discusses the concept of square factors, using 8 as an example. The tutorial then breaks down the process of simplifying the expression by identifying square factors and performing arithmetic operations to achieve a simplified result of 3/2.

What is the result of taking the square root of the square factor of 8?

What is the final simplified form of the expression 3 sqrt 2 / 2 sqrt 2?
