Algebra warm up: pg. 395 # 64 to 68

8.4 Negative and Zero Exponents pg. 390 to 395

So yesterday you learned:

When dividing like bases you subtract exponents and divide the coeffiecients.

ALSO when a fraction is raised to a power--the exponent outside the ( ) gets disributed to the top and bottom the the fraction inside!

Fifth rule of exponents:

Negative exponents:

DON'T forget all the past rules still apply-ONLT NOW- what happens if your exponent in negative?

First try to simplify. If you STILL have a negative exponent--

You have to "flip" the base and exponents position.If on top--it moves to bottom and exponent turns positive

If on bottom--it moves to top ans exponent turns positive.

pg. 391

Try this pg. 391

Sixth rule of Exponents:

ANY variable, monomial, constant raised to the power of 0 is ALWAYS = to 1

What if they combine rules on you?You have to know which to do first!!

pg. 392

In a nutshell: pg. 392

ALSO:-Even exponents yield positive answers-Odd exponents yield negative exponents-Negative exponents--change position of the base and change exponent

to positive-Zero exponent = 1 EVERY TIME
