$6sqrtx$

Consider this example:

Suppose you had $a+5a$

This gives you a total count of a's that is 6 so we have $6a$

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
instead of $a$ we have $sqrtx$ . Not that the brackets serve no purpose.

So $sqrtx+5sqrtx" " =" " 6sqrtx$

How do you simplify [sqrt x] + 5[sqrt x][sqrt x] + 5[sqrt x]?
