IMPOWER is a function in Google Sheets that raises a complex number to a given power. The function takes two arguments:

complex_base: the complex number you want to raise to a power. exponent: the power to which you want to raise the complex number. The syntax for using the IMPOWER function in Google Sheets is:

=IMPOWER(complex_base, exponent)

For example, if you want to raise the complex number 2+3i to the power of 2, you can use the IMPOWER function in Google Sheets as follows:

=IMPOWER(2+3i, 2)

The result would be -5+12i, which is the complex number (2+3i) raised to the power of 2.

Note that if the exponent is not a whole number, the IMPOWER function will return the complex number raised to a fractional power using the complex power formula.
