Radical expressions are similar to adding polynomial expressions because you have a multiple of something to combine. For instance, 3*x really means you have 3 x's to add up x + x + x = 3*x same for 2*x. Therefore there is a total of 5 x's to add up or simply write 5*x. Same concept applies to radical expressions you have a multiple of something to add up.

How it is different, I'm not sure.
