Multiply
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,

Divide
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.

Exponent of exponent
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!

Negative exponents
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
