Exponents How can I find the 20th power on my calculator?

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents
Division with the same base - subtract the exponents
Exponent to an exponent - multiply the exponents
Negative exponent - 1 over the same number to the positive exponent
Zero exponent - anything to the exponent 0 is 1

Good luck,

Paul

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 [=]

Exponents of 10 are entered by pressing [2nd][X^-1] (EE).
For powers of any base, enter the base, press the [^] (below PI) then enter exponent. Use the (-) white key if exponent is negative.

You do not have to do anything special. Just enter what you want and press EXE. Depending on the display type chosen you get
2^20 EXE gives 1048576.000.. for floating point, 1.04857600 *10^06 for Scientific or the same (particular case here) 1.04857600 *10^06 for Engineering. The number of digits after the decimal mark depends on the number of decimal digits chosen in your setup.

To enter exponents of an arbitrary base, use the key that is marked [Y^x]
To enter exponent of 10 press the [EE] key. In scientific notation display, the exponent of the power of 10 is displayed to the right of the mantissa.

Use the ^ key, located above and left of the 7 key. For example, to calculate 2 raised to the 120 power, press 2 ^ 1 2 0 =

Use the general power key marked with X to the y ( look for the image of a key on same line as Power in the screen capture)
You enter a number then press the power key and finally the exponent. If exponent is complicated (fraction, negative or other) enclose the exponent in parentheses.



You aslo have dedicated keys for certain powers and roots (square, square rooot, cube, cubic root)

you type in 5 (or any other number) and then use the carrot (exponent) button that looks like this: ^ and type in your exponent (5) and click the equal button

Hello
Use the general power key labelled as [^], or [X to the y] or [Y to the x] depending on calculator.
3500000 [ / ] [(]7.5 [^] 20[)] [=] gives 1.103678993 E -11
Hope it helps.

For 5 to the 6th power, type
5 ^ 6 =
You should get 15625
