Can someone explain to me the rules for logrithmic functions so I can solve them. I can't seem to understand how the rules work when I try to solve for x.

log (xy) =log x+ log y

Example : log 6 = log (3*2) = log 3 + log 2

log (x/y) = log x- log y

Example

log (3/2) = log 3 - log 2

log (x^p) = p * log x

Example

log (3^2) = 2 log 3

log 1 =0

log (1/x) = -log x

Example

log (1/2) = -log 2

log 3  4 = log 4/log 3
