(s+L sqrt(7))(2+sqrt(5))

Simplify the following expressions.(i) (5+sqrt(7))(2+sqrt(5)) (ii) (5+sqrt(5))(5-sqrt(5)) (iv) (sqrt(11)-sqrt(7))(sqrt(11)+sqrt(7))

Simplify the following expressions. (i) (5+sqrt(7))(2+sqrt(5)) (ii) (5+sqrt(5))(5-sqrt(5)) (iii) (sqrt(3)+sqrt(7))^2 (iv) (sqrt(11)-sqrt(7))(sqrt(11)+sqrt(7))

Simplify the following expressions . i) (5+sqrt(7))(2+sqrt(5)) ii) (5+sqrt(5))(5-sqrt(5)) iii) (sqrt(3)+sqrt(7))^(2) iv) (sqrt(11)-sqrt(7))(sqrt(11)+sqrt(7))

Evaluate : ( sqrt(5) + sqrt(7 ) ) /( sqrt(5) - sqrt(7 ) )

find the value (sqrt(5)+sqrt(7))(2+sqrt(5))

Simplify the following expressions: (3+sqrt(3))(2+sqrt(2))( ii) (5+sqrt(7))(2+sqrt(5))

Simplify the following expressions: (3+sqrt(3))(2+sqrt(2))( ii) (5+sqrt(7))(2+sqrt(5))

Evaluate : ( sqrt(7) + sqrt(5) ) ( sqrt(5) - sqrt(7) )

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