`(sqrt2timessqrt3)(sqrt2-sqrt3)=?`

(2+sqrt2)/(1+sqrt3)times(1-sqrt3)/(1-sqrt3)=?

(sqrt2+sqrt3)(sqrt3+sqrt8)

(1+sqrt2)/(sqrt5+sqrt3)= ((1+sqrt2)xx(sqrt5-sqrt3))/((sqrt5+sqrt3)xx(sqrt5-sqrt3))=

Which of the following is irrational? (a) (2-sqrt3)2 (b) (sqrt2+sqrt3)2 (c) (sqrt2-sqrt3)(sqrt2+sqrt3) (d) (2sqrt7)/7

(2sqrt3 + sqrt2)(2sqrt3-sqrt2)

(3 + sqrt2)(2-sqrt3)(3-sqrt2)(2+sqrt3)

The value of 2(sqrt(2)+sqrt(6))/(3sqrt(2+sqrt(3)))+sqrt(2+sqrt(3))+sqrt(2-sqrt(3))

([(sqrt(2)+i sqrt(3))+(sqrt(2)-i sqrt(3))])/([(sqrt(3)+1sqrt(2))+(sqrt(3)-1sqrt(2))])

( (sqrt(2)+i sqrt(3))+(sqrt(2)-i sqrt(3)) )/( (sqrt(3)+i sqrt(2))+(sqrt(3)-i sqrt(2)) )

The value of (1-sqrt2) + (sqrt2-sqrt3)+(sqrt3-sqrt4)+ ............ + (sqrt15-sqrt16) is
