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.

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 =

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.

There is a way to do it. I believe you go into "complex" or "math" buttons. These buttons are yellow on the calculator. Therefore, to access them you must hit "2nd" then the button.

Better yet, you can also get around this dilemma another way. You can enter "the cubed root of x" by raising x to 1/3.

For example the cubed root of x = x^(1/3). It is best to place parentheses around 1/3 so the calculator knows exactly what you mean.

Another example, the "cubed root of (x + 1)" can be entered by:

(x+1)^(1/3) Note the parenteses around both (x+1) and (1/3). This applies if the radical cover both "x" and "1".

Hope this helps.
