Lesson 3
Product Law & Quotient Law
Example 1:
22 x 23
For the following examples write each product of powers as a single power. Then, evaluate the power.
What do you notice?

What do you notice?
An Experiment
1. Choose a base2. Choose an exponent3. Multiply that power by the same base raised to a different exponent. What's the answer?
Product Law
When multiplying powers with the same base, add the exponents to write the product as a single power.
(a)m × (a)n = (a)m+n

Quotient Law
When dividing powers with the same base, subtract the exponents to write the quotient as a single power.
(a)m ÷ (a)n = am-n
Example 5: 45 ÷ 42
Example 6: (-3)10 / (-3)7
