Answer

$\overline{z}+\overline{w}=8+2i$

Work Step by Step

$z=3-4i$ $;$ $w=5+2i$ $\overline{z}+\overline{w}$ Find the conjugate of the two complex numbers by changing the sign of their imaginary part: $\overline{z}=3+4i$ $\overline{w}=5-2i$ Evaluate the operation: $\overline{z}+\overline{w}=(3+4i)+(5-2i)=(3+5)+(4-2)i=8+2i$
