So, in order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.

Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.

Step 2: Make sure all radicals are simplified.

Step 3: Simplify the fraction if needed.

How do you divide radicals step by step?

Here are the steps to dividing radical expressions.

Ensure that the index of each radical is the same and that the denominator is not zero.

Convert the expression to one radical.

Simplify where possible.

Rationalize the denominator, if necessary.

How do I use the quotient rule?

The Quotient Rule in Words The Quotient Rule says that the derivative of a quotient is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the square of the denominator.

What to do if variable is in denominator?

Correct answer: To solve an equation with a variable in a fraciton, treat the denominator as a constant value and multiply both sides of the equation by the denominator in order to eliminate it.

Is there an intro to rationalizing the denominator?

Intro to rationalizing the denominator. When we have a fraction with a root in the denominator, like 1/√2, it’s often desirable to manipulate it so the denominator doesn’t have roots. To do that, we can multiply both the numerator and the denominator by the same root, that will get rid of the root in the denominator.

Which is an example of an irrational denominator?

Example: has an Irrational Denominator 1 Multiply Both Top and Bottom by a Root Sometimes we can just multiply both top and bottom by a root: Example: has an… 2 Multiply Both Top and Bottom by the Conjugate More

What happens when you multiply the numerator and the denominator?

Multiply the numerator and denominator of the original fraction by the conjugate of the denominator. Distribute the numerators, and FOIL the denominators. The middle terms of the denominator will drop out because they are the “same” in values but opposite in signs. = 7.

How to multiply top and bottom by the denominator?

Multiply Both Top and Bottom by the Conjugate. There is another special way to move a square root from the bottom of a fraction to the top we multiply both top and bottom by the conjugate of the denominator. The conjugate is where we change the sign in the middle of two terms:
