    Help with deriving relationships starting with the identity a^x = e^xlna

    So if I am following you correctly, ln N/ln 10 = log10 (N) or ln X / ln 10 = log 10 X ?

    Help with deriving relationships starting with the identity a^x = e^xlna

    here's where I am at... f(x) = 10^x; 10^x = e^xln10; f′(x) = e^xln10 (ln 10) = 10^x ln 10 then from there I got 10^x 2.303 log 10...

    Help with deriving relationships starting with the identity a^x = e^xlna

    Hi there - it has been quite a long time since I took Calculus. I am trying to brush up and understand where to start with this question: Starting with the identity a^x = e^xlna, derive the relationships between (a) e^x and 10^x; (b) ln x and log x. Note: log x = log10 x unless otherwise...
