Which exponent function?
To enter an exponent of ten, use 2nd [EE].
To raise ten to an exponent, use 2nd [10^x].
To raise e to an exponent, use 2nd [e^x].
To raise an arbitrary number to an exponent, use ^.

Im trying to do a poisson distribution on my ti030xa. i dont care if i have to do it in pieces. i just dont understand how to do the e which is 2.71828 to the -3 exponent times 3 to the fourth power.


You want to enter an exponential of some sort. There is a key for that function. Look for the natural logarithm function whose key is marked [LN]. The exponential function key is accessed through [2nd] or [Shift] followed by [LN].
If exponent is negative, use the change sign key (-) or +/- to enter the negative sign, followed by the exponent.
See the screen capture that follows.

How do i enter an exponent on the


It depends on the base of the power function.
For exponential function use [SHIFT][LN] (e^x) followed by the exponent value. If exponent is negative use the change sign +/- key before exponent.
For a general power, type in the base (number), then press the [Y^x] key followed by the exponent.
For a power of 10, use the [Exp] key. Careful here. For example to enter 1.6x10^(-19), type in 1.6, press the [Exp] key, then the change sign key +/- and the exponent. Press [=]
1 . 6 [Exp] +/- 19 [=]

How do i use e?


On most calculators, a mathematical function and its inverse function share the same physical key. One function is accessed directly by pressing the key, the other function is accessed by pressing SHIFT and the function key.
The exponential function e^x is the inverse of natural log (ln(x))
To access the exponential e^x, press [SHIFT] [LN]. If the exponent is like yours, an expression not simple, enclose the expression in parentheses to ensure that the exponent is the one intended.

How to enter exponents


If you mean an exponent of ten, use the EE function (the shifted function of the "," key, located just above the "7" key. For example, to enter 1.2 times ten to the negative 3, press 1 . 2 2ND [EE] (-) 3

To raise a number to an exponent, use the ^ key located just above the divide key. For example, to calculate 3 raised to the 4th, press 3 ^ 4 ENTER

I have a Texas Instruments TI-84 plus silver edition calculator, and I need to know if it has a exponent key?


If you want to raise a number to another, use the ^ key located just above the divide key.
For natural antilogarithm (exponentiation of e), use 2ND [e^x] (the shifted function of the LN key).
For common antilogarithm (exponentiation of 10), use 2ND [10^x] (the shifted function of the LOG key).
To enter a decimal exponent as part of a number, use 2ND [EE] (the shifted function of the comma key, located just above the 7 key.

Where is the exponent key on Casio fx-115es calculator?


To raise 10 to an exponent, use the 10^x function (SHIFT log). To raise e to an exponent, use the e^x function (SHIFT ln). To raise an arbitrary value to an exponent, use x^y (just above the sin key). To enter an exponent of ten, use the x10^x key to the right of the decimal point.

How do I use a negative exponent when working working with natural exponential functions, on this calculator?


The same way you'd work with positive exponents. The only difference is that a negative exponent has a negative sign, entered with the (-) key just to the right of the decimal point.

The (-) is used to enter negative numbers, not just exponents. The - key is used to subract one value from another.

How do you raise to a power on a Sharp el-738 business calculato?


I don't know about this specific calculator, but there is probably a button on your calculator that has a "y" with an "x" as a superscript (exponent). Or is could be reversed. But you wanted 2^8, you would push the 2 first, then the exponent button, then the 8, and there's your answer.

Good luck.
