Is it possible for two complex numbers to have a real exponentiation?
In other words, if x and y are complex (each have the form a+bi), show that x^y can have a real value, or prove that it is impossible.
Note: i is the imaginary value defined as the number that yields -1 when squared. a and b are any real numbers, but b is not 0.
A complex number is said to have the form a+bi. One solution here uses a number in which a is zero, making the number purely imaginary. If b were zero it would be purely real. Is the purely imaginary number considered complex, even though the purely real number is not?
