LO: SWBAT apply the properties of exponents to
simplify algebraic expressions with integral
exponents.

DOL: Given a set of problems, students will
correctly use the laws of exponents including
product rule, quotient rule, and zero exponent
rule to simplify algebraic expressions with
integral exponents in at least 4 of 5 questions.

A.11B: Simplify numeric and algebraic expressions using the laws of exponents, including integral and rational
exponents.

= 7 x 7 x 7

Exponents represent

Repeated multiplication.

7 times itself 3 times.

Zero Rule

a⁰

Any base with an exponent of zero is = 1

= 1

Proof

6³

6³

6³

6³

= (6・6・6)

(6・6・6)

= 1

​= 6^3-3= 6⁰=1

You can write a power as a product by writing out the repeated multiplication.

● “two to the seventh power.”

● “the seventh power of two.”

● “two raised to the seventh power.”

A Common mistake:

Why is this incorrect?

The exponent tells us how
many times we’re going to
multiply the base times itself.
The correct answer is 2⁷ = 128.
