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)
Find the exact value of log 6 3 + log 6 12 without using a calculator.
