Answer 2

•according to the question

1/root 7-2 = a+b root 7

1/√7 -2 = 1×(√7 +2) / (√7 +2)×(√7 -2) =( √7 + 2)/(7-4) = √7/3 + 2/3

so according to the question we can say that

√7/3 + 2/3 = a+b root 7 = a+ b√7

so 2/3 + ( 1/3 ×√7) = a+ b√7........(1)

and from the following equation (1)

we can get

a = 2/3 and b = 1/3
