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
log x
-2 [log (x+2) + log(x-2)] as the logarithm of a single quantity.
| log x -2 [log (x+2) + log(x-2)] | Show work. | Apply the first law to combine the terms within square brackets into a single log term. |
