    convert 50=5*10 and 15=5*3 so now =log10/3 =log10-log3 =1-log3

    doesn't your calculator have the option to calculate log? if not then u can simplify log(50/15) = log (10/3) = log 10 -log 3 =1-log 3 and u need to know log 3 = 0.477

    then i think, u need to remember atleast these 2 : log 2 = 0.301, log 3 = 0.477

    I'm still trying to figure out the notation. What country are you from?

    You can interpret that in different ways: \[\log_{20}{(5)}\] \[\log_{10}(20/5)\] \[\log_{5}(20)\]

    If it's \[\log_{10}(20/5) = \log_{10}(4)\] , then it is relatively easy.

    If you want help, you will need to clarify what the notation is.

    Okay, so if it is what I think it is, then log(20/5) = 2 log(2) = .602

    \(\log (20/5)=log 4 = log (2^2)=2log2 \\ \text{from the property of log that :} \\ \huge logx^n=nlogx\) and as i mentioned, u should remember log 2 =0.301
