De Moivre tells us that: (cosθ+isinθ)n=cosnθ+isinnθ. So we find: (1+i)4=(√2(cos(π4)+isin(π4)))4., Simple: Let us suppose, x = [(1+i)^2] That makes (1+i)^4 = [(1+i)^2] * [(1+i)^2] i.e., (1+i)^4 = x^2 Lets solve for x. x = (1+i)^2 = 1+(i^2) + 2i ..., Given (1 - i) ^ 4 ((1-i)^2)^2 (1+i^2-2i)^2 (1-1-2i)^2 (-2i)^2 4i^2 4(-1) -4 Online Math Homework Help., Because, i^2 = - 1, and that helps us so much. How? Let's take a look. (1 + i)^2 = 1 + 2i + i^2 = 2i. Therefore (1 + i)^4 = 4i^2 = - 4.
