Laws of Logarithms

Laws of Logarithms:
1. log
a(u v) = loga(u) + loga(v) {The log of a product equals the sum of the logs.}
2. log
a(u/v) = loga(u) - loga(v) {The log of a quotient equals the difference of the logs.}
3. log
a(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.
