\(6 \sqrt{18} +3 \sqrt{50} =6 \sqrt{9*2} +3 \sqrt{25*2} =6*3 \sqrt{2} +3*5 \sqrt{2}\)=18 sqrt2+15 sqrt2=33 sqrt 2
I hope this helps you square root of 18=square root of 3^2.2=3square root of 2square root of 50=square root of 5^2.2=5square root of 26.3square root of 2+3.5square root of 218square root of 2+15square root of 233square root of 2
