Помогите комплексные числа

Answer 1

$z_1^3 = (2+3i)^3 = 8 +36i + 54i^2 + 27i^3 = 8-54 + (36-27)i = -46 + 9i$
$z_2^2=(3-4i)^2=9-24i+16i^2=9-16-24i=-7-24i$
$\frac{-46 + 9i}{-7-24i} = \frac{46-9i}{7+24i} = \frac{(46-9i)(7-24i)}{(7+24i)(7-24i)} = \frac{322-63i-1104i+216i^2}{49-576i^2}$$= \frac{322-216-1167i}{49+576} = \frac{106-1167i}{625}$
