The two are often used interchangeably beyond A-Level, though to be fair, even if it were log10 or for that matter any other base it's just a constant scaling.
A little messy, but ya'll might like it: ∫1+x41dx.

log is used in confusingly different ways between mathematics, engineering and physics to mean both log_10 and log_e. It's a bit of a mess.
