`(sqrt5-3)/(sqrt5+3)times(sqrt5-3)/(sqrt5-3)=?`

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

Show that (sqrt5+sqrt3)/(sqrt5-sqrt3)-(sqrt5-sqrt3)/(sqrt5+sqrt3)=2sqrt15

What is (sqrt5+sqrt3)/(sqrt5-sqrt3)+(sqrt5-sqrt3)/(sqrt5+sqrt3) equal to

(sqrt5+sqrt3)/(sqrt5-sqrt3)=

If 2sqrtx= (sqrt5 + sqrt3)/(sqrt5 - sqrt3)-(sqrt5 - sqrt3)/(sqrt5 + sqrt3) then what is the value of x ?

" 1. 3sqrt(5)times sqrt(5)=

find the values of a and b in each of the following (i) (5+2sqrt3)/(7+4sqrt3) = a-6sqrt3 (ii) (3-sqrt5)/(3+2sqrt5)= asqrt5-(19/11) (iii) (sqrt2+sqrt3)/(3sqrt2-2sqrt3)=2-bsqrt6 (iv) (7+sqrt5)/(7-sqrt5)-(7-sqrt5)/(7+sqrt5)=a+(7/11)bsqrt5

(sqrt(5)+sqrt(3))((3sqrt(3))/(sqrt(5)+sqrt(2))-sqrt(5)/(sqrt(3)+sqrt(2))) is equal to :
