If `((sqrt(a)-sqrt(b))^2+4sqrt(a b))/(a-b)=5/3,` then the value of `a:b` is :

if (4+3sqrt(5))/(sqrt(5))=a+b sqrt(5) then the value of b is

If a=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)),b=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) then the value of a+b is

If (4 sqrt(3) + 5 sqrt(2))/(sqrt(48 ) + sqrt(18))= a + bsqrt(6) , then the value of a and b are respectively

If a=(2 + sqrt(3))/(2-sqrt(3)) and b = (2-sqrt(3))/(2+ sqrt(3)) , then the value of a^(2)+b^(2)+ab is :

If a = (sqrt(5) + sqrt(4))^(-3) and b = (sqrt(5) - sqrt(4))^(-3) , then the value of: (a+1)^(-1) + (b+1)^(-1) is:

If a=sqrt(6+2sqrt(5))-sqrt(6-2sqrt(5)),b=^(3)sqrt(17sqrt(5)+38)-^(3)sqrt(17sqrt(5)-38) then the value of log_(a)b is equal to
