Transcript of GUIDELINES FOR COMPLETING THE ASSIGNMENT ... ASSIGNMENT RAHWAY HIGH SCHOOL MATHEMATICS DEPARTMENT...

Supplies needed for your first day of class

and every day after:

3 Ring Binder or Notebook

Filler Paper

Pencils/Erasers

Scientific Calculator (such as a TI-34)

We STRONGLY recommend you have a

Graphing Calculator (TI 84).

Summer 2017

Due date: September 9th

This packet was created

to help you succeed in

your upcoming

Precalculus class. Many

of the concepts were

taught to you in

previous classes. In your

upcoming math class we

will be building on these

concepts covered in this

packet.

You may find that you

have forgotten some of

these concepts. There

are many resources

available to you on the

internet to refresh your

memory. If you are

confused, be sure to

take the time to ask for

the help needed to

complete them.

This packet will count towards your first marking period grade. The packet will be graded for completeness and accuracy. Your teacher will be looking for supporting work to see that you understand each concept. We have given you our email addresses so you can contact one of us if you have questions. Please do not wait until the first day of school to ask for help! On Friday, September 9th, you will be given an assessment on the topics included in this packet to check for understanding. Have a great summer!

Properties of Rational Exponents

Let a and b be real numbers and let m and n be rational numbers , such that the quantities in

each property are real numbers.

Property Name: Definition:

1. Product of Powers 1. am · an = am + n

2. Power of a Power 2. (am)n = amn

3. Power of a Product 3. (ab)m = ambm

4. Negative Exponent 4. a-m = 1

𝑚 , a ≠ 0

5. Zero Exponent 5. a0 = 1, a ≠ 0

6. Quotient of Powers 6. am/ an = am-n, a≠ 0

7. Power of a Quotient 7. ( 𝑎

𝑏 ) m = am / bm , b≠ 0
