Question

Решите z=-3i
Z=4+4i
Z=-6+3i
Z=-2-5i

Answer 1

Пошаговое объяснение:

Z= - 3i

-3i= 4+4i

-3i-4i=4

-7i=4

i= - 4/7

Z=4+4×(-4/7)=4-16/7=(28-16)/7=12/7

Z= - 3×(-4/7)=12/7

Z= - 3i

-3i=6+3i

-3i-3i=6

-6i=6

i= - 1

Z=6+3×(-1)=6-3=3

Z= - 3×(-1)=3

Z= - 3i

-3i=2-5i

-3i+5i=2

2i=2

i=1

Z=2-5×1=2-5= - 3

Z= - 3×1= - 3
