I know √15 + √15 =2 √15. Now if you wanted to add 3 to the solution, can you.
Say, 3 + 2 √15, would that = 5 √15?

1 apple + 1 apple = 2 apples
1 apple + 1 apple + 1 orange = 2 apples + 1 orange
1rt 15 + 1 rt 15 + 3 = 2 rt 15 + 3
Conclusion
You can add only things that are the same.
Sorry that I don't have a square root sign but I am away from home and this computer cannot access symbols.

no
3+2 â15 is not the same as 5 â15
3 â15 + 2 â15 = 5 â15

no it would be 3 + 2 * the square root of 15.
but
(3 * square root of 15) + (2 * square root of 15) = 5 * square root of 15

If you put brackets around the 3+2, yes.
