Question

Describe the process of rationalizing the denominator. Why do we do this? Does it change the value of the radical? Explain your thoughts

Answer 1

Answer:

hey mate here is your answer:

Step-by-step explanation:

• Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.

Since we have a square root in the denominator, then we need to multiply by the square root of an expression that will give us a perfect square under the radical in the denominator.

Square roots are nice to work with in this type of problem because if the radicand is not a perfect square to begin with, we just have to multiply it by itself and then we have a perfect square.

• Make sure all radicals are simplified.
• Simplify the fraction if needed.

Hope it will help you...
