- Today's lesson is about exponent rules: Multiplying and Dividing.
- Ex. 5 exponent of 2 * 5 exponent of 3. You just add the 2 and 3, which is 5. Then, you have 5 exponent of 5.
- So the rule is that if you are multiplying with exponents that have the same base, then you can just add the exponents. But keep the base the same.
- What about division though?
- I don't get it. Which one do you subtract?
- Ex. 5 exponent of 6 / 5 exponent of 2. You subtract 6-2 and then you get 5 exponent of 4.
- For division, if you have the same base, you subtract your exponents and keep the base.
- Oh, OK. I understand it now!
- So you take the numerator's exponent and then subtract the denominators exponent.
- Now you try! 5 exponent of 2 * 5 exponent of 3.The answer is 5 exponent of 5!
- Now you try! 5 exponent of 5 / 5 exponent of 2.The answer is 5 exponent of 3!
- Ok. I really understand this now!
- Rules: Multiplying: If they have the same base, then you just add the exponents. Dividing: If they have the same base, then you just subtract the exponents.
