1. Найдите частное чисел x=63,12+-0,003; y=5,26+-0,004 2. Комплексные числа z1=3-i; z2=1-√3i (z1+z2; z1*z2; z1:z2)

1) Получим 4 варианта:

x1/y1 = 63,123 : 5,264 = 11,992;

x1/y2 = 63,123 : 5,258 = 12,005;

x2/y1 = 63,117 : 5,264 = 11,991;

x2/y2 = 63,117 : 5,258 = 12,004.

2) z1 + z2 = (3 - i) + (1 - √3i) = 4 - (1 + √3) i;

z1*z2 = (3 - i) * (1 - √3i) = 3 - 3 * √3i - i - √3 = 3 - √3 - (3√3 + 1) * i;

3) z1/z2 = (3 - i) * (1 + √3i) / (1 - √3i) * (1 + √3i) = (3 - 3 * √3i - i + √3) / 4 = 1/4 * ((3 + √3) - (3√3 + 1) i).
