Question

$find \: the \: rationalizing \: factor \: of \: \: \sqrt{2 } + \sqrt{7} - \sqrt{10}$
​

Answer 1

Answer:

Rationalizing factor is a term with which a term is multiplied or divided to make the whole term rational. (√2 + √7 - √10)(√2 + √7 + √10) = (√2 + √7)^2 - 10 = 2√14 - 1. = 55. = 15√2 + 5√7 + √10 + 4√35 is one such rationalizing factor.
