Did you complete the
reading Map test yesterday?
Today – Math MAP test (9:00 am or 2:00 pm)
Now Open!!

GOAL FOR TODAY…….
Goal:
 Be able to apply
properties of
exponents to
generate
equivalent
numerical
expressions
Agenda:
 Review –

Properties of Exponents
There are some basic properties that we
will discuss in this lesson and the next
lesson that deal with “raising a number to
a power”
What do you think?
For example: 35
∙ 37
How do you multiply different powers of
the same number x: if m, n are positive
integers, what is 𝑥 𝑚 ∙ 𝑥 𝑛?
Example: 35
∙ 37
Think of it this way!
35
∙ 37
= 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3
The factors of a power, such as 74, can be
grouped in different ways.
7 • 7 • 7 • 7 =
(7 • 7 • 7) • 7 =
(7 • 7) • (7 • 7) =
Notice the relationship of the exponents in
each product.
74
73 • 71 = 74
72 • 72 = 74
By the definition of exponential notation we
looked at in the previous lesson.
Multiplication Property
We’re the
same!?!?
Example Time
Multiply. Write the product as one power.
Example Time
Multiply. Write the product as one power.
What would happen if there were more than
two terms with the same base? Write an
equivalent expression for each problem.
Can the following expressions be simplified? If
so, write an equivalent expression. If not,
explain why not.
Can the following expressions be simplified? If
so, write an equivalent expression. If not,
explain why not.
WRAP UP
It’s over
already : (
If you have the same bases,
add the exponents when
multiplying.
