4
But what happens if the bigger exponent is on the
bottom?
5
The bigger x is on the bottom, so thats where it
stays!
6
Simplify
The 2 divides into the 6 three times
7
Rule 5 When division is happening inside the
parentheses, distribute the exponent to all
8
Just like with multiplication

10
Remember, apply the exponent to everything, even
the negative
11
Rule 6 Negative exponents If there is a base
with a negative exponent in the numerator, move
it to the denominator and make the exponent
positive

13
The 2 stayed up top since it did not have a
negative exponent!
14
If there is a negative exponent in the
denominator, move it to the numerator and make
the exponent positive

The -2 stays put because it does not have a
negative exponent!
We are multiplying like bases! (Rule 1)
18
The y moves down, changing the -3 to a 3, and the
z moves up, changing the -5 to a 5!
19
Rule 7 Any number raised to the zero power is 1
20

21
Anything raised to the zero power is 1! But be
careful
Because this is 5 times x to the zero power. The
exponent belongs to the x, not the 5!
22
Lets try another Simplify
We must first apply rule 1 on the top!
23
Lets look at that one again
What happens if we apply rule 4?
24

25
When multiplying two expressions, just remember
how to multiply fractions
26
1st multiply across Then simplify
27
Lets try another
28
The trick is Trying to remember all of those
rules and apply them!
29
Now, its your turn Here is your assignment!
