Question #83ff4

1 Answer

Oct 16, 2015

$\frac{7}{5} - \frac{10}{3} i$ $7/5 - 10/3 i$

Explanation:

Sum the real and complex part separately:

Real Part: $1 + \frac{2}{5} = \frac{5}{5} + \frac{2}{5} = \frac{7}{5}$ $1+2/5 = 5/5+2/5=7/5$
Complex part: $\frac{2}{3} i - 4 i = i (\frac{2}{3} - 4) = - \frac{10}{3} i$ $2/3 i -4i = i(2/3-4)=-10/3 i$
