Calculator buttons not working


You are lucky. Calculate the number by which you want to divide (divisor), then press the reciprocal key (1/X) or raise it to the -1 power.

E^ won't work


You are not using it correctly. To calculate the exponential of a number you use the key sequence [SHIFT][LN] to access the exponential function. Then type it the exponent (positive or negative) and close the parenthesis.
You do not use the power key (^)
The exponential function is not affected by the angle unit when you are using real values.

How do I raise the power of 30 on calculator?


If you are using an HP 12c or have the button on the calculator "yx" you first enter the number you wish to raise (y) then enter then the power (x). For instance to find 230 (2 to the power of 30) you input the number 2 then hit the enter key on the calculator, then input 30 and hit the yx button.

If you have another model of calculator the procedure may be similar or the buttons. Play around with it. By the way the solution to 2 raised to the 30th power is 1,073,741,824.

I want to calculate powers on my calculator but am unsure what buttons to press


You have two buttons to calculate powers: The [x^2] calculates the square of a number while the [caret ^] key allows you to calculate any power, be it with integer, fraction or negative exponent.
Both keys are next to one another, one below OPTN and the other below the VARS key.
To calculate roots, you have the square root [SHIFT][x^2] the xroot key [SHIFT] [caret ^] , the CUBE root [SHIFT] [(] , and the inverse key [SHIFT][).

Where is the exponent button


To raise 10 to a power, use 10^x (the 2nd function of the LOG key). To raise e to a power, use e^x (the 2nd function of the LN key). To raise a number to another, use y^x (the key just above the divide key).

Exponent key on the TI-36x Calculator


On the TI-36X there is no rooftop key, there is a yx key. This key is two keys below the on button. To use it, put the number in, press the yx key, put the exponent in, press the equal button.

Keystroke issue with TI BA II +...


ok so when you're typing it into your calc. like that don't type it in without parenthesis.

example:

2^3=8
to find the cube root of 8, you type in 8^(1/3)

DONT type 8^1/3 because that means that you raising the 8 by a one and then dividing that answer by 3
