If a = (sqrt5 +1)/(sqrt5-1) and b = (sqrt5-1)/(sqrt5+1) then find the value of (5a^(2) -3ab +5b^(2))

If a=(sqrt(5)+1)/(sqrt(5)-1) and b=(sqrt(5)-1)/(sqrt(5)+1), the value of ((a^(2)+ab+b^(2))/(a^(2)-ab+b^(2))) is (3)/(4) (b) (4)/(3)(c)(3)/(5)(d)(5)/(3)

If a=(sqrt(2)+1)/(sqrt(2)-1) and b=(sqrt(2)-1)/(sqrt(2)+1) ,then find the value of a^(2)+b^(2)-4ab
