Solve for x in each equation by using the
following properties of logarithms:
logx(ab) = logxa + logxb
a
logx( ) = logxa – logxb
b
m logxa = logx(am)
log10(3x + 10) = log108 + log1011

ln 5 = ln x – ln 3
ln 20 = ln x + ln 5
2 ln x = 4 ln 3
log10(4x + 8) = log10(3x) + log104
2 log2x = 4 log26
ln (x + 2) – ln x = 2 ln 5
log3x – log311 = log3(x – 10)
log5x + log53 = 2 log52
log2(x + 1) – log2(2x) =
ln 6 + ln x =
