2 radical 30
Three times the fifth root of three.
Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
2/3 = sqrt( 4/9 )
3^3*radical(128) = 3^3*radical(2^7) = 3^3*radical(2^6*2) =3^3*2^3*radical(2) = 216*radical(2).
-3*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30

First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
9*radical(3)/2 = 4.5*radical(3) = 7.794 approx.
√3 + √3 = 2√3
