# Just do it rebus

$\Large n = \Large a^{-1}\cdot e^{\frac{\huge it}{\huge s}}$

It is a catchy phrase.

Well, doing some mathematical manipulation:

$n=a^{-1}\cdot e^{\frac{it}{s}}\Rightarrow an=e^{it/s}\Rightarrow\log(an)=\frac{it}{s}\Rightarrow s\log(an)=it$

So I guess the answer is

it's a slogan.

• I argue it should be $\color{white}{s\ln(an)=it\text{ (since the base of the log is currently undefined}}$ (highlight to see spoiler). – boboquack Oct 27 '17 at 9:22
• @boboquack As a pure mathematician, I use log for natural logarithm. ln is an abomination. – Rand al'Thor Oct 27 '17 at 9:28
• @MeaCulpaNay As Rand already explained, actual mathematicians use log to mean natural log. – Gareth McCaughan Oct 27 '17 at 13:44
• @Randal'Thor $log$ is an abomination because it lacks clarity. As a member of the STEM community, clarity should be a very high priority for all of us. You may find it distasteful, but you (and many others) will never be confused about the base if I write $ln$ or $lg$ or $log_{10}$. – jpmc26 Oct 27 '17 at 22:03
• @jpmc26 except I have never seen the lg notation before... – Socratic Phoenix Oct 27 '17 at 22:15
