(a) find value of "a" `(7+3sqrt(5))/(5+2sqrt(5))=1+a sqrt(5)`

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

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

Find the value of a and b if (7+3sqrt(5))/(3+sqrt(5))-(7-3sqrt(5))/(3-sqrt(5)) =a + bsqrt(5)

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

Find the value of a and b if (2+5sqrt(7))/(2-5sqrt(7))=(a+sqrt(7)b)

If a=(2+sqrt(5))/(2-sqrt(5)) and b=(2-sqrt(5))/(2+sqrt(5)) then find value of a+b and b=(2-sqrt(5))/(2+sqrt(5)) then find

Find the value of sqrt(3+sqrt(5))-sqrt(2+sqrt(3))
