Assuming that the base of your log is 10, then the log is approximately -0.602059991. You can simply use the log key on your calculator or use the quotient property which says that, log x/y = log x - log y.
log 1/4 = log 1 - log 4 = 0 - 0.602059991 = -0.602059991

when you write out just "log" with no base, the base is assumed to be 10. your question is asking 10^x = 1/4
so just get a calculator and type in log(1/4) and it will give you the answer above. If you were asking natural log (ln), it would be e^x = 1/4, where e is an actual number (2.718281828)

log(1/4) = log 1 - log 4 = 0 - 2log2 = -2 log2

log(10) (1/4) = log(10)0.25 = log(10)2.5 - 1
= (bar 1).3979.

Base 10
Log (1/4) = log (0.25) = -0.602059991
Natural Logs (base e)
Ln (1/4) = Ln (0.25) = -1.386294361
Hope this helps.

what is the base of your log?

There are easier ways to find this out than asking here. Try a calculator.
