If `(2+sqrt5)/(7+sqrt3)=a+bsqrt3+csqrt5+dsqrt15`, then `a-b+c-d=?`

If (4+2sqrt5)/(4-3sqrt5) = a+bsqrt5 ,then

3/(sqrt3-sqrt2)=asqrt3-bsqrt2

If a+bsqrt5=(2-sqrt5)/(3+sqrt5) , then, a-b=?

If (5+2sqrt(3))/(7+4sqrt(3))=a+bsqrt(3) , then a=-11 , b=-6 (b) a=-11 , b=6 (c) a=11 , b=-6 (d) a=6, b=11

If (5+2sqrt3)/(7+4sqrt3)=a+bsqrt3 , then the value of a and b is

(3+sqrt7)/(3-4sqrt7)=c+dsqrt7 then c+d=

If (4+3sqrt5)/(4-3sqrt5)=-61/29+bsqrt5 then b=

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

If (sqrt7-sqrt5)/(sqrt7+sqrt5)=a+bsqrt(35) , then the value of (a - b) is

( sqrt(2) + sqrt(3)) /( sqrt(2 - sqrt(3)) = a + bsqrt(3) , find the a and b
