Question

find the rationalizing factor of 5-√3​

Answer 1

Answer:

5 + √3

Step-by-step explanation:

A rationalising factor is a term which when multiplied to the given irrational number will make it a rational number.

So, when 5-√3 is multiplied by 5+√3, the resulting number is (5-√3)(5+√3) = {5² - (√3)²} = (25 - 3) = 22 which is rational.
