If you mean sqrt(50)/5 + 3*(sqrt(3))/10 Then my answer is: Let us break down sqrt(50) to sqrt(25*2) So sqrt(25*2)/5 + 3*(sqrt(3))/10 Let us separate the two with two separate radicals: =sqrt(25)*sqrt(2)/5 + 3*(sqrt(3))/10 Let us simply sqrt(25) because that's a perfect square. =5*sqrt(2)/5 + 3*(sqrt(3))/10 The 5 before the sqrt(2) and the 5 in the denominator is cancelled out because basically the 5 is in the numerator. So we're left with sqrt(2) + 3(sqrt(3))/10 Answer: sqrt(2) + (3 sqrt(3))/10 OR sqrt(2) + 3 sqrt(3)/10 I just add ( ) in the numerator for the sake of avoiding ambiguity. I hope I helped.
