Answer 2

6√3

Answer 3

did the 5 become a 6 because you added the 3+3?

Answer 4

radical75+radical3
radical25* radical3+ radical3
5 radical3+radical 3

Answer 5

no that's wrong radical 75 can be simplified to radical 25 and radical 3. That can be simplified to 5 radical 3

Answer 6

what happens to the second radical 3 then?

Answer 7

√75 would simplify to 5√3 and √3 would stay as it is. Imagine there is a 1 in front of the √3. Add 5 +1 to get 6 and then you will keep the radical 3 giving you the answer 6√3.

Answer 8

When adding a radical to another it can not be simplified further unless they are the same number. since they are both radical 3 you can just get rid of the second one
