I just bought my TI-84 calculator so I don't know really well on how to operate it. Please tell me step by step. Thanks

Well, what are you taking the log of?
Say you want to know log (base 7) of 12.
You have to do a change of base because your calculator only has base e (which is the natural log (ln)) and base 10 (which is the common log (log)).
Punch in
ln(12)/ln(7) = 1.27698940827
You could also use
log(12)/log(7) and you would get the same answer.
I just prefer ln for some reason.

Log Calculator With Steps

y = log (base 7) x = log x / log 7
the calculator can't calculate the log in a base other than 10
but use the mathematical formula,
log (base a) b = log b / log a
like
log (base 2) 8 = log 8 / log 2 = 3

For the best answers, search on this site https://shorturl.im/avLQC
the same way you put in any equation there's a button that has "x,t,Ø,n" when you press that, it'll give you the X you need look further down and to the left and you'll see "x^2" key everything else shouldn't be a problem

y = log(base 7)x
Write this like
y = (log(x))/(log(7))

These are good answers, but overcomplicated. Simply press "math" and scroll down to option A which will say "logBASE(".
