If a and b are rational numbers and (sqrt(11)-sqrt(7))/(sqrt(11) +sqrt(7))=a - b sqrt(77) . find the value of a and b.

Evaluate : (sqrt(11)-sqrt(7))/(sqrt(11)+sqrt(7))

If both a and b are rational numbers,Find a and b*(3+sqrt(7))/(3-sqrt(7))=a-b sqrt(7)

In each of the following determine rational number a and b:(sqrt(11)-sqrt(7))/(sqrt(11)+sqrt(7))=a-b sqrt(77) (ii) (4+3sqrt(5))/(4-3sqrt(5))=a+b sqrt(5)

(sqrt(7)+1)/(sqrt(7)-1)-(sqrt(7)-1)/(sqrt(7)+1)=a+b sqrt(7)

In each of the following determine rational number a\ a n d\ b : (i)\ (sqrt(11)-sqrt(7))/(sqrt(11)+\ sqrt(7))=a-bsqrt(77) (ii)\ (4+3sqrt(5))/(4-3sqrt(5))=a+bsqrt(5)

(sqrt(7)-1)/(sqrt(7)+1)=(sqrt(7)+1)/(sqrt(7)-1) Find the value of A and B

If (3sqrt(5)-6sqrt(7))-(2sqrt(5)-11sqrt(7))=asqrt(5)+bsqrt(7), then find the values of a and b.
