Question

I need answer immediately please​

Answer 1

Answer:

(√11 - √7)/(√11 + √7) = a - b√77

rationalising LHS we get

(√11-√7)(√11-√7)/((√11+√7)(√11-√7)) = a - b√77

(11 + 7 - 2√77) / (11 - 7) = a - b√77

(18 - 2√77)/4 = a - b√77

18/4 - 2√77/4 = a - b√77

9/2 - √77/2 = a - b√77

on comparing

a = 9/2, b = 1/2
