Determine a and b if `(5+sqrt3)/(7-4sqrt3)=94a+3sqrt3b`

Find a and b when (5+2sqrt3)/(7+4sqrt3)=a+bsqrt3

(5+2sqrt(3))/(7+4sqrt(3))=a-b sqrt(3)

(5+2sqrt(3))/(7+4sqrt(3))=a-b sqrt(3)

determine a and b if (7+sqrt(5))/(7-sqrt(5))-(7-sqrt(5))/(7+sqrt(5))=a+7b sqrt(5)

Find the value of m and n : if : ( 5+ 2sqrt3)/( 7+ 4sqrt3) = m + n sqrt3
