Question about Texas Instruments TI-86 Calculator

Hello,

If there is no special key reserved for that operation, you can use the raise to an arbitrary power key. This key is represented as [^] ( a caret or accent circonflexe) or [X to the y] or [Y to the x ]. I have just verified : it is primary key accessible directly.

If you want the cube of a number; 2 [^]3 =2x2x2=8.

In your algebra course they must have taught you that the roots of a number (square, cube, fourth, fifth, nth) are equivalents to raising that number to a fractionary power (a power whose exponent is a fraction of the form 1/2 ,1/3, 1/4, 1/5, 1/n etc.)

27[^] (1/3) = cube root of 23 = 3

Hope it helps.

There are several ways to find the cube root of a number on a calculator. On this calculator, we can use the nth root button, by using the yellow shift button with the ^ key. Another way to do this is just to use the ^ key.

For example, the cube root of 8 is performed by the following key sequence: 8, shift, ^, 3.

Another sequence is: 8 ^ (1/3)

Good luck.

If you mean 6 plus cube root of 2 then press

6 + 2 2nd [cube-root] =

The cube root is the shifted function of the 0 key.

6 + 2 2nd [cube-root] =

The cube root is the shifted function of the 0 key.

I assume you want 40 raised to the one-third power?

Three simple ways.

Raise 40 to the one-third power: Press 4 0 y^x ( 1 / 3 ) =

or

Take the cube root of 40: Press 4 0 2nd cube-root = (the cube-root is the shifted function of the 0 key)

or

Take the third root of 40: Press 4 0 2nd xth-root 3 = (the xth-root is the shifted function of the y^x key, located just above the divide key)

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).

Welp on a Ti-93 using the 2nd function click on the function look for the cube root function barring that look for the x root function you can make the x any number 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.

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)

I am guessing, but, find the key that has a 3 to the left of the root symbol, looks like a check mark. Push it, then the number you want to take a cube root of, then enter.
