`5/(sqrt(5)-sqrt(7))`

(1)/(sqrt(2)+sqrt(5)-sqrt(7))

(2sqrt(7))/(sqrt(5)-sqrt(3))

Number of non-zero terms in the exapansion of (5sqrt(5)x+sqrt(7))^(6)+(5sqrt(5)x-sqrt(7))^(6) is __________

show that (sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))times(sqrt(7)-sqrt(5))/(sqrt(7)-sqrt(5)) =frac{(sqrt(7)-sqrt(5))^(2)}{2}

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

(1)/(2sqrt(7)+sqrt(5))-(1)/(2sqrt(5)+sqrt(7)) simplify

Find (x+a)^(5)+(x-a)^(5) . Hence, evaluate (sqrt(6)+sqrt(7))^(5)+(sqrt(6)-sqrt(7))^(5)

Simplify each of the following : (i)(sqrt(2)+1)/(sqrt(2)-1)+(sqrt(2)-1)/(sqrt(2)+1)" "(ii)(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))" "(iii)(2)/(sqrt(5)+sqrt(3))+(1)/(sqrt(3)+sqrt(2))-(3)/(sqrt(5)+sqrt(2))" "(iv)(sqrt(7)+sqrt(5))/(sqrt(7)-sqrt(5))-(sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))

If sqrt(35)=5.9160, then the value of (sqrt(7)+sqrt(5))/(sqrt(7)-sqrt(5))
