taking natural log ... x ln(10) = ln(2) + 1
I would just take logs of both sides
log 10^x = log (2e)
x log10 = log(2e)
x (1) = log(2e)
x = log(2e) <----- nice and compact, should have been a choice
log 10^x = log (2e)
x log10 = log(2e)
x (1) = log(2e)
x = log(2e) <----- nice and compact, should have been a choice
