Continue reading to discover the answer to the question "what is a complex number?" as well as the algebraic and polar forms of complex numbers and how to multiply and divide them. When b=0, z is real, when a=0, we say that z is pure imaginary. If the denominator is c+di, to make it without i (or make it real), multiply with conjugate c-di: (c+di)(c-di) = c 2 +d 2 (10-5i) / (1+i) = 2.5-7.5i . To disclose uncertainty to multiply the expression containing the root of the conjugated to it and apply the difference of squares.
