Rationalising factor of `2/sqrt(5)`

Rationalising factor of 1/sqrt(3)

The simplest rationalising factor of 2sqrt(5)-sqrt(3) is 2sqrt(5)+3( b) 2sqrt(5)+sqrt(3)(c)sqrt(5)+sqrt(3) (d) sqrt(5)-sqrt(3)

Write the rationalisation factor of sqrt(5)-2

Write the rationalisation factor of 7-3sqrt(5)

The simplest rationalisation factor of (2sqrt(2) - sqrt(3))

The rationalisation factor of 2+sqrt(3) is 2-sqrt(3) (b) sqrt(2)+3(c)sqrt(2)-3(d)sqrt(3)-2

The simplest rationalising factor of sqrt(3)+sqrt(5) is sqrt(3)-5( b) 3-sqrt(5)(c)sqrt(3)-sqrt(5)(d)sqrt(3)+sqrt(5)

If rationalizing factor of 3sqrt(5) is multiplied by rationalizing factor of 5sqrt(2^(3)) ,then the resultant is
