Given the complex numbers w = a + bi and z = c + di, what is the result of the subtraction w - z?
The subtraction of two complex numbers w and z is defined as w - z = (a - c) + (b - d)i.
The multiplication of two complex numbers w and z is defined as w.z = (ac - bd) + (ad + bc)i.
The division of two complex numbers w and z is defined as w/z = (ac + bd)/(c^2 + d^2) + (bc - ad)/(c^2 + d^2)i, where z is not equal to zero.
a. (a - c) + (b - d)i
b. (a + c) + (b + d)i
c. (a - c) - (b - d)i
d. (a + c) - (b + d)i

A resposta correta é a alternativa A) (a - c) + (b - d)i. A subtração de dois números complexos é definida como w - z = (a - c) + (b - d)i. Portanto, basta subtrair as partes reais e imaginárias dos números complexos w e z para obter a resposta.
