Sú dané komplexné čísla \( a=\sqrt2\left(\cos⁡160^{\circ}+\mathrm{i}\cdot\sin⁡160^{\circ}\right) \), \( b=3\sqrt2\left(\cos⁡150^{\circ}+\mathrm{i}\cdot\sin150^{\circ}\right) \) a \( c=2\left(\cos240^{\circ}+\mathrm{i}\cdot\sin240^{\circ}\right) \). Vypočítajte \( a\cdot b\cdot c \).
\(12\left(\cos190^{\circ}+\mathrm{i}\cdot\sin190^{\circ}\right) \)
\(12\left(\cos10^{\circ}+\mathrm{i}\cdot\sin10^{\circ}\right) \)
\(12\left(\cos⁡10^{\circ}-\mathrm{i}\cdot\sin10^{\circ}\right) \)
\(12\left(\cos⁡190^{\circ}-\mathrm{i}\cdot\sin190^{\circ}\right) \)
