If (4+3sqrt(5))/(4-3sqrt(5))=a+b sqrt(5)

If (4+3sqrt(5))/(sqrt(5))=a+b sqrt(5), bis

if a and b are rational numbers and (4+3sqrt(5))/(4-3sqrt(5))=a+b sqrt(5) then find the value of a and b

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)

If (4+2sqrt5)/(4-3sqrt5) = a+bsqrt5 ,then

The square root of (7+3sqrt(5))(7-3sqrt(5)) is sqrt(5)(b)2(c)4(d)3sqrt(5)
