Evaluate `sqrt(2)(sqrt2+1)-sqrt(2)(1+sqrt(2))`

Evaluate (1/sqrt(2))/(1/sqrt(2)+sqrt(3))

If sqrt(2)=1.414 and sqrt(3)=1.732, then the value of (1+sqrt(2))/(sqrt(3)+sqrt(2))+(1-sqrt(2))/(sqrt(3)-sqrt(2)) is

Evaluate 1/(1+sqrt(2))+1/(sqrt(2)+sqrt(3))+1/(sqrt(3)+sqrt(4))

Evaluate : (1)/(1sqrt(2)+2sqrt(1))+(1)/(2sqrt(3)+3sqrt(2))+......+(1)/(399sqrt(400)+400sqrt(399))

find the value of 1/(sqrt(2)+sqrt(3))-1/(sqrt(2)-sqrt(3))

find the value of 1/(sqrt(2)+sqrt(3))-1/(sqrt(2)-sqrt(3))

If (0,1),(1,1) and (1,0) be the middle points of the sides of a triangle,its incentre is (2+sqrt(2),2+sqrt(2))( b) [2+sqrt(2),-(2+sqrt(2))](2-sqrt(2),2-sqrt(2)) (d) [2-sqrt(2),(2+sqrt(2))]

(sqrt2-1)/(sqrt2+1)times(sqrt2-1)/(sqrt2-1)=?

Find: the 10 th term of the G.P.sqrt(2),(1)/(sqrt(2)),(1)/(2sqrt(2))
