You can calculate the cube root by raising to the one-third power. For example, to calculate the cube root of 125, press 1 2 5 y^x 3 1/x =

The y^x key is just above the 9 key. The 1/x key is just above that.

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 =

Use the cube-root function, which is the shifted function of the square-root key (third row, second column). For example, to find the cube root of 8, press

SHIFT [cube-root] 8 =

SHIFT [cube-root] 8 =

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).

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)

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.

To find the cubed root (or any root) of a number, use the root() function.

If you want the cubed root of 125, you would type:

root(125,3)

If you want the cubed root of 125, you would type:

root(125,3)

The TI-89 has one function to find whatever root you want of a number.

To find the cubed root of say...64, you would type:

root(64,3)

To find the cubed root of say...64, you would type:

root(64,3)

You use the y^x (y to the x) key along with the 2nd function key. That does the opposite operation.

So, let's pick something we know the answer to as an example. How about the cube root of 8? We know 8 = 2 X 2 X 2, so the cube root of 8 will be 2.

Here's how:

8 2nd y^x 3 =

The display will show 2.

The three is the root you want. You can put in any number, with 2 being the square root, 3 the cube root, etc.
