How To Write Cube Root In Wolfram. Try replacing the 1/3 power with cuberoot [ ( (x+2) (x^2+4x +1))]. For a cube root of a negative value there are three roots possible.

Preferable to use a superscript instead of the root: Luckily the formulas i gave in the start of this post work no matter what cube root you use in place of $\sqrt[3]{x}$, so normally you don’t actually define a “principal root” when working with complex numbers; Cuberoot can be evaluated to arbitrary numerical precision.
The Below Table Contains All The Information You Need To Type This Symbol On The Keyboard On Word For Windows Pc.
As one loops around the origin in units of 2π, one jumps from one root to the next. Only on microsoft word documents, type 221b and press alt and x keys to make cube root symbol ∛. Alternatively, we can access mathematica’s cuberoot function, for example, by typing “cube root” instead of using the power ^(1/3), as in the previous example.
I Assume This Pertains To Wolfram|Alpha.
The cube root of a number can be computed using newton's method by iteratively applying. I'm not quite sure what to make of your statement i want to have the input exactly as provided to the students. In standardform surd[x,n] formats as $\sqrt[n]{x}$.

Two of them are complex. Try replacing the 1/3 power with cuberoot [ ( (x+2) (x^2+4x +1))]. This shortcut works only on ms word.
This Demonstration Shows A Construction Of Using A Ruler With Two Marks (Red And Black ) At A Distance 1 Unit Apart, Constrained To Lie On The Axis And The Blue Line.
X^ (1/3) or, nthroot (x,3) be very careful though. Luckily the formulas i gave in the start of this post work no matter what cube root you use in place of $\sqrt[3]{x}$, so normally you don’t actually define a “principal root” when working with complex numbers; To type the cube root symbol on word for windows, simply press down the alt key and type 8731 using the numeric keypad, then let go of the alt key.

Cuberoot can be evaluated to arbitrary numerical precision. I have found that the root mathematica chooses can be influenced by the bounds chosen for a plot3d graphic. Richard, all of these work for me in wolframalpha:
