Answer 1

a)aducem la acelasi numitor si avem
(6√5+3+10√3-5) /15  : (5-3-10√3-6√5) /15
=(6√5+10√3-2)/15 · (-15) /(6√5+10√3-2)=-1

b)5 / (5√6+2√3)  ·(√3/15+3√6/6-2√6/6)
=5 /(5√6+2√3) ·(2√3+5√6) /30
=5/30=1/6
c) (√2+5√5/2√6 -3√3/2√10-4√2/√15)·√2
=2+10√15/12-6√15/20-8√15/15
numitorul este 60
=120/60=2
