化简 3/(-4i)

解答

化简

\frac{3}{- 4 i}

\frac{3}{4} i

求解步骤

\frac{3}{- 4 i}

乘以共轭根式

\frac{- i}{- i}

= \frac{3 ( - i )}{- 4 i ( - i )}

化简

\frac{3 ( - i )}{- 4 i ( - i )} : \frac{- 3 i}{- 4}

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

Rewrite in standard complex form:

\frac{3}{4} i

= \frac{3}{4} i

∣ 4 x - 5 ∣ = ∣ - x + 5 ∣

f a c t or 10 x^{3} + 8 x^{2} - 6 x

f a c t or 80 r^{2} - 125

3 = \frac{g}{- 4} - 5

f a c t or x^{2} + 52 x + 100
