The hard part of this one is reading the question. I'm going to assume those root 5s are in the numerators.


\frac 3 4 √(5) - √(3) + \frac 2 4 √(5) + √(3) = A √(5) + B√(3)

Two fourths? Really? OK.


\frac 3 4 √(5) - √(3) + \frac 2 4 √(5) + √(3)


=(\frac 3 4 + \frac 2 4)√(5) + (-1 + 1)√(3)


=\frac 5 4 √(5)

Answer: A=5/4, B=0
