`30/(5sqrt(3)-3sqrt(5))`

rationalise the denominator (5sqrt(3)+3sqrt(5))/(5sqrt(3)-3sqrt(5))

Express each one of the following with rational denominator: (i) (30)/(5sqrt(3)-\ 3\ sqrt(5)) (ii) 1/(2sqrt(5)-\ sqrt(3))\

Rationalise the denominator of each of the folloowing expressions : ( 30 )/( 5sqrt3- 3sqrt5)

(2)/(sqrt(3)+sqrt(5))+(5)/(sqrt(3)-sqrt(5))=x sqrt(3)+y sqrt(5)

If ((x-2sqrt(6))(5sqrt(3)+5sqrt(2)))/(5sqrt(3)-5sqrt(2))=1, then the

1/(sqrt(3)+sqrt(2))-2/(sqrt(5)-sqrt(3))-3/(sqrt(2)-sqrt(5))

(sqrt(3)-sqrt(5))(sqrt(3)+sqrt(5))/(sqrt(7)-2sqrt(5))

(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))

4 sin 27^(0)= 1) sqrt(5+sqrt(5))+sqrt(3-sqrt(5)) 2) sqrt(5-sqrt(5))+sqrt(3+sqrt(5) 3) sqrt(5+sqrt(5))-sqrt(3-sqrt(5)) 4) sqrt(5+sqrt(5))+sqrt(3+sqrt(5)
