6. OpenSessame

You add the exponents...\[X ^{a}*X ^{b}=X ^{a+b}\]

7. babyblue123

so you're only multiplying the numbers and not the exponents?

8. OpenSessame

No you are multiplying the exponents too, but the rule multiplying exponents is that its like adding them together.

9. OpenSessame

Solve it and ill tell you if you did it right:)

2x^8+8x^4

11. OpenSessame

No...Try again...Add the exponents and multiply the constants.
