Question

Dau coroana pentru cine reușește sa îmi rezolve astea...Va rog am mare nevoie de ele gata pana maine

Answer 1

Rez1=4
Imz1==-6
_____________
Re z2=7
Imz2=3
______________________________________________----
z1barat  =4+6i
z2barat=7-3i
_________________________________--
lz1l=√(4²+(-6)²=√(16+36=√52=√4*13=2√13
lz2l=√(7²+3²)=√49+9=√58
____________________________
z1+z2=4-6i+7+3i=11-3i
z1-z2=4-6i-(7+3i)=4-6i-7-3i=-3-9i
z2-z1=7+3i-(4-6i)=7+3i-6+6i=1+9i
