If you want to know the root, you must first know the square, cube and n power.

The square of 2 equals 4 (to be exact, the square of 2 equals 4).

4 to the second power equals 2.

In general, unless otherwise specified, the root is to open the quadratic. Short for prescription.

The operation symbol of the root is the root symbol. See the figure below.

The second half belongs to the expansion, but you can watch it or not. If you are interested in mathematics and learn it well, you can have a look. I'll learn it later anyway.

The third power of 2 is equal to 8 2 3 = 8.

Then the third power of 8 equals 2.

Open the cubic, write a smaller 3 in the upper left corner of the root sign, and so on.

If the n power of 2 is equal to m (the n power of 2 is the product of n 2)

Then m versus n equals 2.

If the y power of x is equal to z

Then z drives to the y power, which is equal to X.
