3 times the square root of 2

If we factor 60, we get 60 = 2 * 2 * 3 * 5 So sqrt ( 60 ) = sqrt (2 * 2 * 3 * 5) = sqrt (2 * 2) * sqrt (3 * 5) = 4 * sqrt( 15 ) ____________________________________________________________ actually if you do by just using the simpler way you should get 2 radical 15 since , 60 has the closest perfect square of 4 and non perfect of 15 this is how you should solve radical 60 = radical 4 times radical 15 radical 60 = simplify the 4 to 2 and leave radical 15 So , radical 60 = 2 radical 15 not what is above .

√3 + √3 = 2√3
2 radical 30
radical 3 or 6
-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
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.
3root(6)+5root(2) you really answered it yourself!
first the two numbers have the same radicand which is radical 2 so we just add the numbers before them to become 7 radical 2
The square root of 12 may be simplified to 2 times the square root of 3.

3^3*radical(128) = 3^3*radical(2^7) = 3^3*radical(2^6*2) =3^3*2^3*radical(2) = 216*radical(2).
5 times 3 times 2 times 2. Or 2 radical 15.
-3*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30
