53 means the product of 3 factors of 5 = 5 x 5 x 5

3. The Laws Of Exponents The laws of exponents tell us how to simplify
expressions involving
exponents.
There are 7 laws of exponents.

4. Exponential form: raising a base to a power stands for
repeated multiplication of the base times itself.

8. The Laws of Exponents:

9. #1: Multiplying Bases: If you are multiplying bases with the same base, KEEP the BASE & ADD the EXPONENTS!
So, I get it! When you multiply bases, you add the exponents!

10. Try these:

11. SOLUTIONS

12. Questions What is the first law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.

13. #3: Dividing Bases: When dividing bases with the same base, KEEP the BASE & SUBTRACT the EXPONENTS!
So, I get it!
When you divide bases, you subtract the exponents!

14. Try these:

15. SOLUTIONS

16. Questions What is the second law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.

17. #3: Power of a Power: If you are raising a power to a power, you multiply the exponents!
So, when I take a Power to a power, I multiply the exponents

18. Try these:

19. SOLUTIONS

20. Questions What is the third law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.

21. #4: Product Rule of Exponents: Raising a product to a power means raising all of the factors to the power and then multiplying.
So, the power of the product is the product of the powers.

22. Try these:

23. SOLUTIONS

24. Questions What is the fourth law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.

25. #5: Quotient Rule of Exponents: Raising a quotient to a
power means raising the numerator and denominator to the power.
So, when I take a Power of a Quotient, I apply the exponent to all parts of the quotient.

26. Try these:

27. SOLUTIONS

28. Questions What is the fifth law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.

29. #6: Law of Negative Exponents: A base raised to a
negative power is the reciprocal of the base to the positive power.
So, when I have a negative exponent, I take the reciprocal and change the power to a positive.

30. Try these:

31. SOLUTIONS

32. SOLUTIONS

33. Questions What is the sixth law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.

34. #7: Zero as an exponent: Anything to the zero power is 1.
So whenever I raise anything to the zero power it is always 1!

35. Try these:

36. SOLUTIONS

37. Questions What is the seventh law of exponents? When can I use it?
When can I not use it?
Give an example of where I use it.
Give an example of where I can’t use it.
Why does it work? Give an example.
