Hi, I know the basic laws of logs but just wanted some clarification on a few things; your help would be much appreciated :) (warning, these questions may seem stupid!)(adsbygoogle = window.adsbygoogle || []).push({});

I know that [itex] \log{xy} = \log{x} + \log{y} [/itex]

but does [itex] 4\log{xy} = 4\log{x} + 4\log{y} [/itex] OR [itex] = 4\log{x} + \log{y} [/itex] ?

Again, I know that [itex] \log{xy} = \log{x} + \log{y} [/itex]

but does [itex]- \log{xy} = - ( \log{x} + \log{y}) [/itex] OR [itex]= - \log{x} + \log{y} [/itex]

Again, I know these questions may seem stupid, my head tells me that it is the first case for both but I do not know for certain.

Thanks :)
