How to rationalize the numerator. Things To Know About How to rationalize the numerator.

Step 1: To rationalize the denominator, we have to multiply both the numerator and the denominator by the conjugate of the denominator. Remember that to find the conjugate, all we have to do is to change the sign that goes between the terms. Step 2: Perform the multiplication by distributing to both the numerator and denominator. 1. Multiply Both Top and Bottom by a Root. Example: 1 √2 has an Irrational Denominator. Let's fix it. Multiply top and bottom by the square root of 2, because: √2 × √2 = 2: Now the denominator has a rational number (which is 2). Done!

What we have here is a square root of an entire fraction. The first step is to apply the Quotient Rule of Square Roots. This allows us to generate a fraction with a distinct numerator and a denominator with radical symbols. QUOTIENT RULE OF SQUARE ROOTSTo rationalize a numerator, you must multiply the fraction by a form of 1 that eliminates the irrational number in the numerator. For example, if the numerator is √2, you would multiply by (√2)/(√2) to get rid of the square root. 4. Can you give an example of rationalizing a numerator?

Sure, for example, if we have the fraction 3/√2, we can rationalize the numerator by multiplying both the numerator and denominator by √2. This gives us (3*√2)/ (√2*√2) = (3√2)/2. Now, the radical is in the denominator and the fraction is rationalized. 5.
