How do you get a cube, fourth, fifth root in latex?

In summary, to type a cube root in LaTeX, use the command \sqrt[3]{x}. To get a fourth root, use the command \sqrt[4]{x}, and to write a fifth root, use the command \sqrt[5]{x}. You can also get higher roots by changing the number inside the square brackets, such as \sqrt[6]{x} for the sixth root. There is also a shortcut for typing roots in LaTeX using \sqrt{x} for square roots and \sqrt[n]{x} for nth roots.
