The given expression is a complex expression and we can prove the given expression equal to 1 by using definition.
What is i in complex number?
a+ib, often known as the generic form of complex numbers, is how complex numbers are expressed. In the complex numbers a+ib form, a represents the real component of the number, b represents the imaginary part, and i is defined as√(-1). Complex numbers can take a variety of shapes.
Write the general form of complex number.
z=a+bi is the general form of complex number
As by definition
i^2=-1
So
i^4=(i^2)^2
=(-1)^2
=1
