Объяснение:

w = $w=\frac{2(1-i)}{1+i} + (1+i)$

Домножим числитель и знаменатель дроби на комплексное число, сопряжённое знаменателю

$w=\frac{2(1-i)*(1-i)}{(1+i)*(1-i)} + (1+i) = \frac{2(1^{2}-2i+i^{2})}{(1^{2}-i^{2})} + (1+i) = \frac{2(1-2i-1)}{(1+1)} + (1+i) = \frac{2(-2i)}{2} + (1+i) = -2i + 1+i = 1-i$
