Step-by-step explanation: Rationalising 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. Reply
Step-by-step explanation:
Rationalising 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.
