8.3 Laws of Exponents: Dividing Monomials pg. 383 to 389

So yesterday you learned:

Raising a power or monomial to a power!

What did that mean?

MEANS you would start with a set of ( ) and then distribute the exponent to each part of the expression inside

The third rule of exponents:

Quotients of powers property:

That means now you will be dividing like bases which means you are subtracting the exponents!

(like cancelling out what occurs on the top and the bottom)

Using numbers as bases pg. 384

Using Variables as bases pg. 384

Quotients of Monomials:

Use the same rule before---when dividing like bases you subtract the exponents

BUT also make sure to treat the coefficients like numbers and divide them too!

Try this pg. 385

Again word problems!!!!--Just substitute what you need to and simplify according to ALL of the exponent rules you need!!

pg.385

Powers of a Fraction:

This is like raising a power to a power (applying distributive property to exponents)

BUT what is inside the ( ) is a fraction and the "rule" applies to the top and the bottom of the fraction!

(SOOO applying the exponent using distributive property to everything inside the ( ) on the top AND on the bottom)

Fourth Rule of Exponents:

pg. 386

Try this pg. 386

Now lets try some... pg. 387 # 5-16

DON'T forget you may have to use some of the past rules!
