# Rules For division

In the previous section we have divided two powers with

the same base using properties of division and

multiplication .

We can also divide by subtracting the exponents .

To divide powers with the same base, keep the base and

subtract the exponent in the denominator from the

exponent in the numerator .

Example: Divide

Solution : Subtract the exponents of x

8-2=6

Write the base with the difference of exponents .

Therefore

## Zero as an Exponent :*

Zero can be an exponent . Any power with a zero

exponent is always equal to 1.

Example: multiply

Solution : always write 1 for the power with a 0 exponent.
