Laws of Logarithms
Laws of Logarithms:
1. loga(u
v) = loga(u)
+ loga(v)
{The log of a product equals the sum of the logs.}
2. loga(u/v)
= loga(u)
- loga(v)
{The log of a quotient equals the difference of the logs.}
3. loga(ur
) = r loga
(u)
Use the above properties of logarithms to
write
logax
+2 loga
(y+1) - 3 loga
z as the logarithm of a single quantity.
| logax +2 loga (y+1) - 3 loga z | = Show work. | Apply the third law to the last two terms. |
