15 radical 2
factor the 18. 18=2x3x3. Take out the 3 because it is squared. 5x3 radical 2=15radical2
3√2
3√2
3 times the sqrt 2
2 radical 2
The SQRT(18) in radical form is 3*SQRT(2), where SQRT represents the radical symbol.
The concept of a factor makes proper sense only in the context of integers. Otherwise, any non-zero number can be factor of any other number. For example, radical 7 is a factor of radical 18 since radical(180) = radical(7) * radical (18/7)
3 times the square root of 2
3*SQRT(2)
3*SQRT(2)
√18
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*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30

12 radical 2 you multiply 6 and 2 :)
3^3*radical(128) = 3^3*radical(2^7) = 3^3*radical(2^6*2) =3^3*2^3*radical(2) = 216*radical(2).
