化简 4(3/2)^{-1}

解答

化简

4 (\frac{3}{2})^{- 1}

\frac{8}{3}

十进制

2.66666 \dots

求解步骤

4 (\frac{3}{2})^{- 1}

使用指数法则:

a^{- 1} = \frac{1}{a}

(\frac{3}{2})^{- 1} = \frac{1}{\frac{3}{2}}

= 4 \cdot \frac{1}{\frac{3}{2}}

使用分式法则:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

= 4 \cdot \frac{2}{3}

4 \cdot \frac{2}{3} = \frac{8}{3}

= \frac{8}{3}

s im pl i f y a + b - c - b - c + 2 c - a

f a c t or f (lo g_{10} (4 - x^{2}))

\frac{3}{10} \geq k - \frac{3}{5}

6 \cdot (x + 1) = 10 \cdot (x - 3)
