$ln 432 ~~ 6.0684$

Suppose you know:

$log 2 ~~ 0.30103$

$log 3 ~~ 0.47712$

$ln 10 ~~ 2.302585$

Then:

$(ln 432)/(ln 10) = log 432 = log (2^4 3^3) = 4 log 2 + 3 log 3$

So:

$ln 432 = (ln 10)(4 log 2 + 3 log 3)$

$color(white)(ln 432) ~~ 2.302585*(4*0.30103 + 3*0.47712)$

$color(white)(ln 432) ~~ 6.0684$
