Question

Apply De-moiver's theoren to simplify
{(cos 3 theta + i sin 3 theta)⁴ (cos 4 theta+ i sin 4 theta)⁵( cos 5 theta + i sin 5 theta)⁴
$\frac{ { \cos(3 \: theta) + \: i \: \sin(3 \: theta) }^{4} ( { \cos(4 \: theta ) - \: i \: \sin(4 \: theta) }^{5} }{ { \cos(4 \: theta) + \: i \: \sin(4 \: theta) }^{3}( { \cos(5 \: theta) + i \sin(5 \: theta) }^{ - 4} }$
