Find power of complex number online with step by step solution
Our online calculator lets you to find power of complex number with step by step solution.
To use calculator you should choose representation of complex number (algebraic, trigonometric or exponential) and
enter corresponding data. We also represent some basic knowledge of complex numbers.
Suppose we have complex number
To find its n-th power
one need to calculate expression:
To accomplish this task, one can use short multiplication formulas. For example,
However, for big values of n it would be simplier to use de Moivre's formula:
As expected, to use this formula, complex number should be given in trigonometric form.
Finally, the simplest way to find n-th power of complex number is to
use exponential representation:
Given a complex number z in
form. Find zn, where n=
