simplify 1/(3+4i)

Solution

simplify

\frac{1}{3 + 4 i}

Solution

\frac{3}{25} - \frac{4}{25} i

Solution steps

\frac{1}{3 + 4 i}

Multiply by the conjugate

\frac{3 - 4 i}{3 - 4 i}

= \frac{1 \cdot ( 3 - 4 i )}{( 3 + 4 i ) ( 3 - 4 i )}

Simplify

\frac{1 \cdot ( 3 - 4 i )}{( 3 + 4 i ) ( 3 - 4 i )} : \frac{3 - 4 i}{25}

= \frac{3 - 4 i}{25}

Rewrite in standard complex form:

\frac{3}{25} - \frac{4}{25} i

= \frac{3}{25} - \frac{4}{25} i
