化简 (-4)/(7i)

解答

化简

\frac{- 4}{7 i}

\frac{4}{7} i

求解步骤

\frac{- 4}{7 i}

乘以共轭根式

\frac{- i}{- i}

= \frac{- 4 ( - i )}{7 i ( - i )}

化简

\frac{- 4 ( - i )}{7 i ( - i )} : \frac{4 i}{7}

= \frac{4 i}{7}

Rewrite in standard complex form:

\frac{4}{7} i

= \frac{4}{7} i

(3 x) ln (2) = ln (34)

\frac{1}{x - 2} < \frac{2}{3 x - 9}

x^{2} - x = 3 x

f a c t or 4 c^{2} - 1

∣ 2 a + 7 ∣ + 7 = 4
