Question

If z1 = 7+5i and z2 = 6-4i2, the value of z1+z2 is…… A) -4+7i B) 70+50i C) 60+50i D) 14+10i

Answer 1

if. Z1 and Z2 are two complex number such that | Z1 | = | Z2 | + | Z1 - Z2 | then. a) Im[ Z1/Z2 ] = 0. b)Re[ Z1/Z2 ] = 0. c) Im[ Z1/Z2 ] = Re[ Z1/Z2 ] d) none of these

I also want the answer of the same question
