Ответ:
Объяснение:
1)
Z1+Z2=(5-3i)+(-1+6i)=5-3i-1+6i=4+3i
Z1-Z2=(5-3i)-(-1+6i)=5-3i+1-6i=6-9i
Z1*Z2=(5-3i)(-1+6i)=5*(-1)+5*6i-3i*(-1)-3i*6i=
=-5+30i+3i-18i²=-5+33i-18i²
Z1/Z2=(5-3i)/(-1+6i)
2)
Z1+Z2=(3+7i)+(5+2i)=3+7i+5+2i=8+9i
Z1-Z2=(3+7i)-(5+2i)=3+7i-5-2i=-2+5i
Z1*Z2=(3+7i)(5+2i)=3*5+3*2i+7*5i+7i*2i=
=15+6i+35i+14i²=15+41i+14i²
Z1/Z2=(3+7i)/(5+2i)
