Exponent of complex numbers Given two integers, which may be negative, zero, or positive, a and b (taken in any reasonable format, including inputting a plain complex number), convert it to a + bi where i is the imaginary number (square root of negative one). Then, raise it to the power of a third (positive integer) input variable, c as to (a + bi)c. You should then end up with something like d + ei. You must then output, or return, d and e in any reasonable format (including outputting a plain complex number).

Input and output may be taken or outputted in any order.

Examples:

5, 2, 2 -&gt; 21, 20
1, 4, 2 -&gt; -15, 8
-5, 0, 1 -&gt; -5, 0
