What's with the poor rating? Obviously, you spilled something into it, or you just don't know how to use it.

On 83, 83+, 84, 84+, 84+SE
calc is set to scientific notation.
click "mode" and switch from "sci" to "normal"

### I cant figure out the exponential form for 16

I am not sure what you mean. Even politicians use the term exponential so it has become blurry.
16=2^4 The power function is related to the exponential.
16=1.6*10^1 Scientific notation. Scientific notation is an exponential display format.

### My TI84 plus silver edition calculator is giving me an incorrect sign whenever I do an exponential function. When I type in -25^2, it gives me -625 instead of 625. How do I fix this?

It's giving you the correct answer. It's calculating the negative of 25 squared. 25 squared is 625, and the negative of that is -625.

If you want to calculate the square of negative 25, you need to tell the calculator that.

Press ( (-) 2 5 ) ^ 2 ENTER .

### I am using my Casio fx-300MS and have somehow gotten into the display where it puts my answers in exponential form; 5+5 = 1.0 exp10 to the 1. How do I return to getting my answers in standard form?

Display Format

To change the exponential display format, press the [MODE] key 3 times.

Fixed number of decimal places:

Press 1: Scientific Notation: 0

Press 2: SCI: 0

Press 3: NORM

You will then be prompted for NORM 1 or NORM 2. CHOOSE NORM 1

To return the calculation mode and setup to the initial defaults, press [SHIFT] [CLR] [2]

[=]. This will return the calculator to the following settings:

Calculation mode COMP

Angle unit Deg

Exponential display format Norm 1

Fraction display format a b/c

Decimal point character Dot

### Hi, I have a Casio calculator fx-991MS giving me wrong answers!

Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

### Need Help Solving Exponential Functions ASAP!!!!

You can calculate =4^1.2 in Excel and get 5.278031643
And also in Excel you can determine what the square root of 2 is (2.506628274631) and then in Excel = 5 ^ 2.506628274631 = 56.5012395907155.

I know this is late but maybe it will help later. Assuming I am doing it right. Thanks!

### Half-life exponential problem. Can't get the same answer as example

Hello,
Here is how you enter it.
[+/-]0.693/8x4[2ndF][e^x][=] result is 0.7071588193 or as you wrote 0.7071
some calculators show an error message if you enter the [+/-] (the negative of a number before the number itself).
In that case enter 0.693 then press [+/-]. the calculator should put a small - sign before the 0.
You can try
0.693[+/-][x]4[/]8[2ndF][e^x][=]

Hope it clarifies things.
