Rules of Exponents!

1. Rules of Exponents! Mr. O’Riley

2. 4 Basic Rules • Multiply • Divide • Exponent of Exponent • Negative Exponents • Exponents Video • Authors Page • Resources

3. Multiply • Simplify the expression • Rewrite this as (x*x*x)(x*x*x*x*x)= • Did you notice that 3 + 5 = 8? • So, our rule is: • Be careful! We must have the same base for each exponent. So, • Click here to give it a try! Quit

4. Multiply- Practice Answer Key Quit

5. Divide • Simplify the expression • Rewrite this as (x*x*x*x)/(x*x)= • Did you notice that 4 – 2 = 2? • So, our rule is • Remember, just like multiplication, we must have the same base. • Click here to give it a try! Quit

6. Divide- Practice Answer Key Quit

7. Exponent of Exponent • Simplify the expression • Rewrite this as (x*x*x)(x*x*x)= • Did you notice that 3*2 = 6? • So, our rule is • We only have one base here, so we don’t worry about similar bases. • Click here to give it a try! Quit

8. Exponent of Exponent- Practice Answer Key Quit

9. Negative Exponents • Simplify the expression • This one is a bit more tricky than the rest- your expression will become a fraction! • Take your expression and change the exponent to a positive. Now take 1 over your new expression. • So becomes • Now, our rule is • Click here to give it a try! Quit
