Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\frac{1}{2}+\frac{\sqrt{3}}{2}; \frac{1}{2}-\frac{\sqrt{3}}{2}i$$

Answer

1/2+sqrt(3)/2;1/2-(sqrt(3)*IM)/2

Solution


Use this rule: \(\frac{a}{b} \times c=\frac{ac}{b}\).
\[\begin{aligned}&\frac{1}{2}+\frac{\sqrt{3}}{2}\\&\frac{1}{2}-\frac{\sqrt{3}\imath }{2}\end{aligned}\]
