Simplify `1/(sqrt1+sqrt2)+1/(sqrt2+sqrt3)+1/(sqrt3+sqrt4)`

Determine the value of ............... (1)/(sqrt1 +sqrt2) +(1)/(sqrt2 + sqrt3) +(1)/(sqrt3 + sqrt4) + ……+ (1)/(sqrt120 + sqrt121)

1/(1-sqrt2-sqrt3)=

1/(1+ sqrt2 + sqrt3)

The value of { 1/(sqrt6 - sqrt5) - 1/(sqrt5 - sqrt4) + 1/(sqrt4 - sqrt3) - 1/(sqrt3 - sqrt2) + 1/(sqrt2 - 1)} is :

(sqrt2 +1)/(sqrt3)

Simplify (1/2+1/sqrt2-sqrt3)/(sqrt3-1/sqrt2-1/sqrt3)

Simplify 1/sqrt2+1/(sqrt2+sqrt4)+1/(sqrt4+sqrt6)+1/(sqrt6+sqrt8)

Simplify sqrt((sqrt(2)+1)/(sqrt(2)-1))

Simplify: (1)/(1+sqrt(2))+(1)/(sqrt(2)+sqrt(3))+(1)/(sqrt(3)+sqrt(5))
