Use the root function in the MATH MISC menu.

To find the 5th root of 32: enter 5 then the root function and then 32 and then ENTER to get 2.

    And for the cube root, use 3 instead of 5.

How to calculate cube root on simple calculator
That depends on how simple a calculator. I'll give some examples below for calculating the cube root of 8.

On a TI-86, press 3 2nd [MATH] F5 MORE F4 8 ENTER

If the calculator has a "^" or "y^x" key, raise 8 to the 1/3 power. Again, on the TI-86, press 8 ^ ( 1 / 3 ) ENTER

If the calculator has a logarithm key, take the logarithm, divide it by three, then take the antilogarithm. Again, on the TI-86, press 2nd [e^x] ( ln 8 / 3 ) ENTER

On a slide rule, place the hairline over the number on the K scale and read the cube root on the D scale.

How do I find the cube root button on my TI- 86
Hello,
There is a relation between roots and fractionary powers.

2nd root (square root) of X = X^(1/2) power 1/2
3rd root (cubic root) of X = X^(1/3) power 1/3
4th root of X = X^(1/4)
...
n-th root of X = X^(1/n)

Use the raise to arbitrary power key labeled as a caret [^] or [X to the y] or [Y to the x]
Hope it helps.

What is the cube root function on the ti-86

I'm trying to learn how to get a cubed root on my calculator. I've looked up a lot of different ways of doing it.. but what does ^ mean?!
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.

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.

HOW TO FIND CUBE ROOT
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.
