SOURCE: 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.

SOURCE: Cube roots

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.

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).

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.

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 =

[square-root] is the key just to the left of the divide key.

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)
