We will continue to explore other types of operations on complex numbers. This section will focus on performing multiplication and division on complex numbers.

Basic concepts: Exponents: Zero exponent: $a^0 = 1$, Rationalize the denominator , Find the difference of squares: $(a - b)(a + b) = (a^2 - b^2)$,

Related concepts: Imaginary zeros of polynomials,

- 1.Multiplying complex numbersa)$(3+i)\times(1+3i)$b)$(1-\sqrt{2}i)\times(-2+3\sqrt{2}i)$c)$(6-5i)\times(6+5i)$
- 2.Dividing complex numbersa)$(1+2i)\div(3-i)$b)$\frac{5-\sqrt{5}i}{-4+\sqrt{5}i}$c)$\frac{2-3i}{3i+2}$
- 3.Given that $z=5+6i$, determine $\overline{z}\cdot z$
- 4.Given that $w=2-5i$, $z=3+6i$ determine $w \cdot \overline{z}$
