15 radical 2
The SQRT(18) in radical form is 3*SQRT(2), where SQRT represents the radical symbol.
5sqet(2) + sqrt(18) NB sqrt(18) = sqrt(2 x 9) = sqrt(2)Sqrt(9) = 3sqrt(2) Hence 5 sqrt(2) + 3sqrt(2) = 8sqrt(2)
factor the 18. 18=2x3x3. Take out the 3 because it is squared. 5x3 radical 2=15radical2

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)
