simplify (-1)/(-9i)

Solution

simplify

\frac{- 1}{- 9 i}

- \frac{1}{9} i

Solution steps

\frac{- 1}{- 9 i}

Multiply by the conjugate

\frac{- i}{- i}

= \frac{- 1 \cdot ( - i )}{- 9 i ( - i )}

Simplify

\frac{- 1 \cdot ( - i )}{- 9 i ( - i )} : \frac{i}{- 9}

= \frac{i}{- 9}

Rewrite in standard complex form:

- \frac{1}{9} i

= - \frac{1}{9} i

5 x^{2} - 30 x - x + 6

\frac{- 9}{15} - \frac{- 12}{5}

\frac{3}{2} + \frac{3}{2}

(\frac{x ^{3}}{y ^{2}})^{(- 1)}

\frac{2 ( x + 1 )}{7} + \frac{3 ( 2 x - 5 )}{8} = 0
