化简 (1/y)/(\frac{y-6){6y}}

解答

化简

\frac{\frac{1}{y}}{\frac{y - 6}{6 y}}

\frac{1 \cdot 6}{y - 6}

求解步骤

\frac{\frac{1}{y}}{\frac{y - 6}{6 y}}

使用分式法则:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

= \frac{1 \cdot 6 y}{y ( y - 6 )}

约分:

y

= \frac{1 \cdot 6}{y - 6}

s im pl i f y \frac{r + 2}{r + 4} - \frac{3}{r + 1}

s im pl i f y 3 (1 + k) + 10 (5 k + 6)

\frac{96}{7}

s im pl i f y (4 x - 3) + (2 x - 4)

e x p an d (x^{2} + \frac{2}{x})^{12}
