integer value expression. You can also use the exponential operator **.

are SQL numeric value expressions that specify the values for the base and exponent
arguments of the POWER function. See
If base numeric-expression-1 is zero, the exponent numeric-expression-2 must be
greater than zero, and the result is zero. If the exponent is zero, the base cannot be 0, and the
result is 1. If the base is negative, the exponent must be a value with an exact numeric data
type and a scale of zero.
