1. 8.1 Laws of Exponents Whenever we have variables which contain exponents and have equal bases, we can do certain mathematical operations to them. Those operations are called the “Laws of Exponents” b x b = basex = exponent

2. Laws of Exponents It is very important that you not just memorize laws of exponents. You MUST understand how they were discovered and why they work. Let’s begin...

3. Example 1

4. First Law of Exponents – Product of Powers - “When you multiply the same base, you keep the base and ADD the exponents.”

5. Example 2

6. Second Law of Exponents – Power of a Power - “To find a power to a power, keep the base, and MULTIPLY the exponents.”

7. Let’s try some... and show work!!!

8. Let’s check...

9. REMINDER... Don’t let yourself be tricked by this one!!!

10. Example 3

11. Third Law of Exponents – Power of a Product - “To find a power of a product, find the power of each factor and multiply.
