What is a Rational Denominator

Rationalize denominator is a method that is used to reduce irrational numbers. It is basically used to simplify the fraction after eliminating radical or imaginary numbers from the denominator so that you can easily find the given problem.

The rationalization method is used in algebra to simplify the denominator value from the given mathematical expression, whether the question is radical/radical or sum/radical, radical/sum, etc.

When Do We Rationalize the Denominator

Rationalization of the denominator is a common method that is used when an algebraic expression is not simplified because of its denominator value.

When expressions contain square roots or cube roots, we use this method to remove the radical from the denominator to simplify it. In the same way, when solving equations or inequalities, rationalizing the denominator is necessary to eliminate radicals and make problems easy to solve.

How to Rationalize the Denominator

To calculate the rationalized denominator, first we need to understand the type of question that requires a solution. According to the given problem we decide which method to use for finding a solution that simplifies the denominator.

To rationalize the denominator, take the denominator value from the given expression and change its sign from positive to negative or negative to positive (this value is called conjugate or conjugacy factor).

Let's discuss the steps of calculation that you rationalize for the denominator. These steps are:

Step 1: As per the given mathematical expression, the conjugate factor is multiplied or divided with the denominator or numerator of the given expression.

Step 2: After multiplying or dividing the conjugate factor, simplified them using mathematical operations.

Step 3: Now your denominator value is simplified, you can further solve it to make the given expression more simpler.

Additionally, you can use our rationalize the denominator calculator to simplify irrational numbers in the denominator for further calculation, which is totally free!

Practical Example of Rationalize Denominator

Example:

Rationalize the given expression

$$ \frac{15 \times \sqrt{13}}{7 \times \sqrt[5]{9}} $$

Solution:

$$ \frac{15 \times \sqrt{13}}{7 \times \sqrt[5]{9}} $$

$$ \frac{15 \times \sqrt{13}}{7 \times \sqrt[5]{9}} \times \frac{\sqrt[5]{9^4}}{\sqrt[5]{9^4}} $$

$$ \frac{15 \times \sqrt[10]{(1343046721)}}{7 \times 9} $$

$$ 0.2390 \times \sqrt[10]{30074733} $$

Frequently Ask Questions

What is rationalization?

Rationalization is the process that transforms an expression into a simpler form by eliminating radicals (square roots, cube roots, etc.) from the denominator using a conjugate factor.

Change the expression to remove any irrational or complex components.

How do you Rationalize the Denominator of 1/(2+√3)?

To rationalize the denominator the conjugate of a given expression is 2 - √3. Now multiply and divide the conjugate factor with the given number.

$$ \frac{1}{2 + \sqrt{3}} \times \frac{2 - \sqrt{3}}{2 - \sqrt{3}} $$

After multiplying, simplify the given expression.

$$ \frac{1 . (2 - \sqrt{3})}{(2 + \sqrt{3}) . (2 - \sqrt{3})} $$

$$ =\; \frac{2 - \sqrt{3}}{4 - 3} $$

$$ =\; \frac{2 - \sqrt{3}}{1} $$

So, the rationalized form of 1 / 2 + √3 is 2 - √3.

How do you Rationalize the Denominator of 1/√7?

To rationalize the denominator the conjugate of a given expression is √7. Now multiply and divide the conjugate factor with the given number.

$$ \frac{1}{\sqrt{7}} \times \frac{\sqrt{7}}{\sqrt{7}} $$

After multiplying, simplify the given expression.

$$ =\; \frac{1 . \sqrt{7}}{\sqrt{7} . \sqrt{7}} $$

$$ =\; \frac{\sqrt{7}}{7} $$

So, the rationalized form of 1/√7 is √7/7.

How to rationalize the denominator of a square root?

For the calculation of the square root, we rationalize the denominator method and multiply and divide the conjugate factor of the denominator by the given expression.

  1. Check the expression in the denominator that contains the square root.
  2. Multiply with both the numerator and the denominator to its conjugate of the denominator.
  3. Simplify expression using mathematical operations.

Let's discuss with an example 1/√2.

$$ \frac{1}{\sqrt{2}} \times \frac{-\sqrt{2}}{-\sqrt{2}} $$

Simplify the expression:

$$ =\; \frac{-\sqrt{2}}{2} $$

So, the rationalized form of 1/√2 is -√2/2.

How to rationalize a cube root denominator?

To rationalize the denominator of a cube root, first, multiply both the numerator and the denominator with its conjugate factor to eliminate the cube root from the denominator. Here are the steps to rationalize the denominator of a cube root:

  1. Identify the expression in the denominator that contains the cube root.
  2. Multiply both the numerator conjugate factor of the denominator with the given expression
  3. Simplify the resulting expression after multiplying.

Let's understand an example 1/3√3 to rationalize the cube root denominator.

$$ \frac{1}{3\sqrt{2}} \times \frac{3\sqrt{4}}{3\sqrt{4}} $$

$$ =\; \frac{3\sqrt{4}}{2} $$

So, the rationalized form of 1 /3√2 is 3√4 / 2.
