-3*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30
3^3*radical(128) = 3^3*radical(2^7) = 3^3*radical(2^6*2) =3^3*2^3*radical(2) = 216*radical(2).
50 = 2*25 so sqrt(50) = 5*sqrt(2)
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.
5 radical 3 is just a number.So, asking this is the same as asking 'What are some equivalents to 3?' One could answer 2 * 3 / 2. But this reduces to 3.The situation is the same for your question. One could offer some multiple of 5 radical 3 as an answer but, being a multiple, it would reduce to 5 radical 3.radical 3 is approximately 1.732 but not exactly 1.732 so one cannot say, for instance, that 5 radical 3 = 5 (1.732) = 8.660. In fact, there is not way of expressing radical 3 with a finite number of decimal places. So no-one can write radical 3 = 1.732.... exactly.5 radical 3 is the best one can do.
3√2 is already in it's simplest form, but if you want to express it as a single radical, it would be: 3√2 = √(32)√2 = √(32 * 2) = √(9 * 2) = √18
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 radical 2

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)
√3 + √3 = 2√3

50 = 2*25 so sqrt(50) = 5*sqrt(2)
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.
5√2*5√2=5*5*√2*√2=5*5*2=25*2=50
-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5
