simplify 5/(6+2i)

Solution

simplify

\frac{5}{6 + 2 i}

Solution

\frac{3}{4} - \frac{1}{4} i

Solution steps

\frac{5}{6 + 2 i}

Multiply by the conjugate

\frac{6 - 2 i}{6 - 2 i}

= \frac{5 ( 6 - 2 i )}{( 6 + 2 i ) ( 6 - 2 i )}

Simplify

\frac{5 ( 6 - 2 i )}{( 6 + 2 i ) ( 6 - 2 i )} : \frac{30 - 10 i}{40}

= \frac{30 - 10 i}{40}

Apply the fraction rule:

\frac{a + bi}{c} = \frac{a}{c} + \frac{b}{c} i

= \frac{30}{40} + \frac{- 10}{40} i

Simplify

\frac{30}{40} + \frac{- 10}{40} i : \frac{3}{4} - \frac{1}{4} i

= \frac{3}{4} - \frac{1}{4} i
