After that press the log key again and then type in 4. Your method is actually the most efficient.
The parenthesis after the g will appear when you press the LOG button.
How to type log base in ti 84. Use the new any base functionality to compute a log of any base. The TI-84 doesnt directly support different bases for logarithms but you can just do log xlog 2 or ln xln 2 since those are equal to the base 2 log of x. Try ALPHA F2 scroll to 5th option.
Was this answer helpful. As you are aware the TI-83 does not have logBASE in the MATH menu like the TI-84 CE does. But you can calculate other log bases on your TI-83.
Lets do a number you know the answer to. Since 3³ 27 we know that log₃ 27 3. Just divide log 27 by log 3 and you have your number.
The logbase function on a TI-89 doesnt exactly correspond one-on-one to a TI-84 Plus logBASE function. The logbase function doesnt change the base of the given. How to calculate base 10 and any base logarithms on the TI84 Plus CE CalculatorIf you are thinking about joining the military read my article about joining.

Thankfully there is a simple formula called the change of base formula that allows you to calculate any logarithm on your calculator.
Your calculator may have simply a lnor logbutton but for this formula you only need one of these. For example to evaluate the logarithm base 2 of 8 enter ln8ln2 into your calculator and press ENTER. You should get 3 as your answer.
Try it for yourself. 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.
Ln 12ln 7 127698940827. You could also use. Log 12log 7 and you would get the same answer.
I just prefer ln for some reason. This cannot be changed with a button but it can be with a formula. If you want log base 4 10 start out by pressing the log key and then typing 10.
Then press the division key. After that press the log key again and then type in 4. In order to find the log with a power of ten use the LOG button.
For example to find log105 type log 5. The parenthesis after the g will appear when you press the LOG button. How to enter a log base 10 problem on a TI 84 plus calculator.
Use something like base 2 log of 39 Or click on Show source just above this solution to see what I typed to get the log to display properly. There are an infinite number of possible bases for logarithms. Since we obviously cant have an infinite number of buttons for all these logarithms.
So far the only way I know is to go log xlog2 y. For instance if Im trying to find log to the base 2 of the number 24. But this is time consuming when you have a long equation with lots of log to the base to 2s in it.
