# Powers and Roots

Powers are entered by putting a superscript number after the value.

5²

The inverse of a number can be entered using the inverse symbol ⁻¹ (`Ctrl`+`I`).

3⁻¹

Powers can also be calculated using the ^ symbol. This allows the power to be an equation.

5^(6−2)

If your keyboard does not have a `^` key you can use `*` twice.

Square roots can be calculated using the symbol (`Ctrl`+`R`).

√2

n-th roots can be calculated by putting a subscript number before the root sign.

₃√2
