Locate e on the calc?

Question

How do i find e on the calc? to figure out 1030e^0.056

Answer 1

If you want "e^(some number)" then it will either be a button labeled "e^x" or inverse of ln (one button labeled "inverse" and another for "ln").

The Windows built-in calculator, in "scientific" mode, does e^x by selecting the "Inv" (inverse) checkbox and then pressing the "ln" (natual log) button.

Answer 2

To get e, start with 0 and press "exp" twice.
The first time you get 1, and the second time you get e.


Now to do your problem

1: On a handheld:
You enter .056, then = and press the "exp" button, and multiply the result by 1030.

2: On your Windows system:
Click on "View" on the toolbar, and click on "Scientific" to get a bunch more keys.
Exponential and the Natural Logarithm are inverse functions.
To do an exponential with base e, you check the "inv" box and then "ln".

Here is the sequence of keystrokes:

.056
=
check "inv" box near the upper left corner
ln
* (multiply)
1030
=

I got 1089.3256142487...

By the way, the other buttons are hexadecimal, octal, binary, radians, and hyperbolic.

Answer 3

It's the third button from the top on the right hand side.
That's of course if you have a casio fx-115 ms.
It will usually be in the same place as the "Ln" function, just using the inverse or shift key.

Answer 4

Your calculator should have an e button.

If it doesn't, just memorize e (since e is just a constant):
2.718281828459045...

You can round that as desired. And keep in mind it actually has an infinite number of digits after the decimal.

Answer 5

Windows calculator does not have 'e'. Use google calculator:

Answer 6

Each calculator is different, so I'm not sure.

Answer 7

you need a scientific calculator, which would have a button 'e^x'
