√5 (Minus) √3
divided by
√3+√5

Answer 1

The most obvious way to simplify this fraction is to multiply the top and bottom by √3 - √5. This will give you minus 2 in the denominator, and in the numerator:

(√5 - √3)(√3 - √5) = (2√15) - 8

Since we have -2 in the denominator, we end up with

4 - √15, very close to zero.
