how do i isolate t?
(1.065)^t = 1000/875
thanks!
Look at the trick of rewriting it in terms of exponentials and logarithms in your textbook.
Hint: log(a^b) = b * log(a)
it’s not a school question or homework.
actually i’m working and a coworker asked me…
i found a formula on the net…
ln(1.065^t) = ln(1000/875)
etc.
thanks though!
t=log (1000/875)/log 1.065
they dont need to be natural logs…any will do
