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.

Take your pick.

The key is marked "x-superscript-y" and is located near the upper-right corner of the keyboard

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 .

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

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.

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!

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.
