MathBot Answer:
Evaluated
\(\displaystyle \frac{3}{4} + \frac{7}{10 \cdot \left(\frac{2}{5} - \frac{-i}{2}\right)} = \frac{3}{4} + \frac{7 \cdot \left(4 - 5 i\right)}{41} \)
Expanded
\[\frac{3}{4} + \frac{7}{10 \cdot \left(\frac{2}{5} - \frac{-i}{2}\right)} = \frac{235}{164} - \frac{35 i}{41}\]
\(i\) is the imaginary unit, defined as \(i^2 = -1\).
