Question

if Z1=4+3i and Z2=4-3i find geometrically the values of Z1+Z2 and Z1-Z2​

Answer 1

Answer:

we have Z1=4+3i

Z2=4-3i

Z1+Z2=4+3i+4-3i

Z1+Z2=8

Z1-Z2=(4+3i) -(4-3i)

Z1-Z2=4+3i-4+3i

Z1-Z2=6

Answer 2

ANSWER

z

1

=3+4i

z

2

=−4+3i

z=z

1

+z

2

∴z=(3+4i)+(−4+3i)

∴z=(−1+7i)

∴∣z∣=5

underroot 2
