if `a` and `b` are rational numbers and`(4+3sqrt5)/(4-3sqrt5)=a+bsqrt5` then find the value of `a` and `b`

Text Solution

Verified by Experts

`(4+3sqrt(5))/(4-3sqrt(5))= ((4+3sqrt(5)))/((4-3sqrt(5))) xx(4+3sqrt(5))/(4+3sqrt(5))`
`= ((4+3sqrt(5))^(2))/((4)^(2)- (3sqrt(5))^(2))=((4+ 3sqrt(5)))/(16-45) = ((4+3sqrt(5))^(2))/((-29))`
`= ((4)^(2) + (3sqrt(5))^(2) + 2 xx 4xx 3sqrt(5))/(k
