How do you type in the natural logirithim for math equations in the calculator?
Ok question is worded wrong, but I'm trying to type in the natural log for math to divide into a number but I get unusual numbers. For example LN 0.5 / 5730 equals -0.000121. That's what the answer is but when I type it in my calculator I get -1.2096E-4. What am I typing in wrong? Is it the way I'm inputting the numbers??
There's a certain way of typing the problem into the calculator though. I can't get it the other way because I get different number answer
How do I get it to display without E in that case? I have a TI-84 Plus calculator.
On the equation it says to approximate the answer and -0.000121 appears not -9.3466..

The answer in the calculator comes out to be the same, it is just given in exponent form
-1.2096E-4 = -1.2096 * 10^-4 = -0.00012096
There must be a setting in your calculator to change how the answer is displayed.

It is the same answer, so not sure I understand your question.
It is just a different way of writing it with mathematical notation.
It is the same as one million, it can be written any of the following ways:
1,000,000
1 x 10^6
1.0E6
They are all the same number!

type as ln(0.5/5730)
put those brackets properly. . . . and the answer for this is -9.34661799 and not -0.000121. . . .
putting brackets in proper way means a lot to calci
