Solution: (4+5i)+(3–4i)=(4+3)+(5–4)i=7+i We write: $$\mathbb{C} = \{x + yi : x, y \in \mathbb{R} \}.$$, Two complex numbers $z$ and $w$ are equal if, $$z=w \Leftrightarrow Re z = Re w, Im z = Im w.$$. Therefore, $$i^n = i ^{4a + b} = i^{4a} \cdot i ^b = 1 \cdot i^b = i^b \quad b\in\{0,1,2,3\}, a \in \mathbb{Z}$$, $$(-2i^{1023} – 3i^{343}) ( -7i^{234} + i^{456}).$$, $1023$ by dividing with $4$ gives the rest $3$, that is, $$i^{1023} = i^{4 \cdot 255} \cdot i ^3 = 1 \cdot (-i) = -i.$$, $$i^{343} = i^{4 \cdot 85 } \cdot i^3 = 1 \cdot (-i) = -i,$$, $$i^{234} = i^{4 \cdot 58 } \cdot i^2 = 1 \cdot (-1) =-1,$$, $$(-2i^{1023} – 3i^{343}) ( -7i^{234} + i^{456}) =( -2 \cdot (-i) – 3 \cdot (-i)) (-7 \cdot(-1) + 1) $$, $$ i + i^2 + i^3 + i^4 = i + (-1) – i + 1 = 0$$, $$\underbrace{i + i^2 + i^3 + i^4 }_{=0} + \underbrace{i^5 + i^6 + i^7 + i^8 }_{=0} + i^9 +i^{10} = 0 + 0 + i^9 +i^{10} $$, $$= i^{4 \cdot 2} \cdot i + i^{4 \cdot 2} \cdot i^{2} $$.
