1. 4.3 Laws of Exponents
Romans 8:24-25 For in this hope we were saved.
Now hope that is seen is not hope. For who hopes for
what he sees? But if we hope for what we do not
see, we wait for it with patience.

3. Remember that logs are exponents.
Therefore, these laws should make sense ...
1) log a (AB) = log a A + log a B
4. Remember that logs are exponents.
Therefore, these laws should make sense ...
1) log a (AB) = log a A + log a B
⎛ A ⎞
2) log a ⎜ ⎟ = log a A − log a B
⎝ B ⎠
5. Remember that logs are exponents.
Therefore, these laws should make sense ...
1) log a (AB) = log a A + log a B
⎛ A ⎞
2) log a ⎜ ⎟ = log a A − log a B
⎝ B ⎠
3)
c
log a (A) = c log a A
6. Logs can be manipulated using these laws
to either expanded form or combined form.
