simplify 1/(7i)

Solution

simplify

\frac{1}{7 i}

- \frac{1}{7} i

Solution steps

\frac{1}{7 i}

Multiply by the conjugate

\frac{- i}{- i}

= \frac{1 \cdot ( - i )}{7 i ( - i )}

Simplify

\frac{1 \cdot ( - i )}{7 i ( - i )} : \frac{- i}{7}

= \frac{- i}{7}

Rewrite in standard complex form:

- \frac{1}{7} i

= - \frac{1}{7} i

\frac{1}{3} 1

x^{4} \times x^{5}
