化简 1/((3i)^3)

解答

化简

\frac{1}{( 3 i ) ^{3}}

\frac{1}{27} i

求解步骤

\frac{1}{( 3 i ) ^{3}}

化简

(3 i)^{3} : - 27 i

= \frac{1}{- 27 i}

乘以共轭根式

\frac{- i}{- i}

= \frac{1 \cdot ( - i )}{- 27 i ( - i )}

化简

\frac{1 \cdot ( - i )}{- 27 i ( - i )} : \frac{- i}{- 27}

= \frac{- i}{- 27}

Rewrite in standard complex form:

\frac{1}{27} i

= \frac{1}{27} i

\frac{4 ( 5 + x )}{3} = 2 x + 2

2 x^{2} + 9 x + 4 \geq 0

x + \frac{1}{5} = \frac{3}{5}
