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.

### 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 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.
