Please note that for the model of calculator that is listed here, no such button exists. Instead you must press the power button which looks like a rice hat or an arrow pointing up. It looks like this: ^.

It is right below the directional pad, and to input your values you will first enter your base and then the power button, followed by the exponent. here's an example:

5 to the power 9.3 = Answer
5^4.3 =
as an answer you should get about 1012.91 followed by more decimals. Hope it helps.

How can I find the square root of 39 on my ti-30xa? Also I would like to know how to find the cube of 9482... Help


Square root of 39: Press 3 9 [square-root] =
[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =
[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =

How do i get the ca756 to go to a power other than 2? I can get a number squared but not cubed or more.


there should be a button that has an x with a y where the two would be, i believe its above the delete button. that symbol is the same as x^2 (x Squared) except you input whatever you need to as the power in place of y. so hitting x^y followed by a 3 should cube your original x.

Want to know how to calculate a number raised to a power


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)

How do i do a number 'to the power of 1/2 or 2/3? cheers Brad


Power 1/2 is the same as square root: You can use the square root key to the left of the square key.
Similarly power 1/3 is the cube root. You use the [SHIFT][Square root] key sequence.
Power 2/3 is the square of the cube root, or the cube root of the square.

More generally, you can use the universal power key, marked with X with a raised white rectangle. It is between X square and log.

Ex: Calculate 15^(2/3)
15 [X with raised rectangle] 2 [/] 3 [)] [=]; the result is 6.082
The last parenthesis closes the left parenthesis introduced by the calculator.
Alternatively you can use the cube root and the x-root selections available under the MATH menu.(selections 4 and 5)

How to use the exponent key on a casio fx 300ES calculator ?


The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).
  1. You enter the base (the number to be raised to a power).
  2. You press the [X to ] power key.
  3. You close the parenthesis (the right one).
  4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]

How to find cube root.


Hello,
What we call roots: square, cube ,fourth roots, etc. can be shown in algebra to be equiavlent to powers with fractionary exponents where numerator is 1 and denomonator an integer.
square root of a = a to the power 1/2
cube root of a = a to the power 1/3
n-th root of a = a raised to the power 1/n, n integer different from 0.

How to use calculator to calculate cube root?
If you do not have a specific (shortcut) key for it you use the key to raise to an arbitrary power [^ ], sometimes shown as [x^y]. The exponent will be 1/3. Do not replace 1/3 by its decimal approximate.

Cube root of 27 is entered as 27 [^ ] (1/3)

Hope it helps.

I need to know the square root of 50y Cubed


Hello,
The question is not clear. What is the value of y?. The calculator cannot help if y is not known. I will give you a few hints for this algebra problem:
1. Taking the square root is equivalent to raising to the 1/2 power.
2. Power of a product is equal to the product of the powers. (X*Y)^a=(X^a) times (Y^a)
3. (X^a)^b =X^ (a*b)

Hope it helps.
