A Huge ASS

-2 √5 + 3 √5 = (-2 + 3) √5 = 1 √5 = √5

Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.

1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.

5 + (-3) + (-5) = -3

3 plus 4 is 7, not 5.

4√5 + 4√5 = 8√5.

2+3=5.

-3 + 7 = 5

It is: (2*3)+5 = 11

5 + -8 = 3 + 12 -3 is not equal to 15

Yes.

factor the 18. 18=2x3x3. Take out the 3 because it is squared. 5x3 radical 2=15radical2

No, 1 + 2 + 3 + 4 + 5 = 15.

-5 + 3 = -2

(-5)/(3) = -12/3
