化简 ((3.19cm)/s)/(10cm)

解答

化简

\frac{\frac{3.19 c m}{s}}{10 c m}

\frac{319}{1000 s}

求解步骤

\frac{\frac{3.19 c m}{s}}{10 c m}

使用分式法则:

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

= \frac{3.19 c m}{s \cdot 10 c m}

约分:

c

= \frac{3.19 m}{s \cdot 10 m}

约分:

m

= \frac{3.19}{s \cdot 10}

= \frac{3.19}{10 s}

化简

\frac{3.19}{10 s} : \frac{319}{1000 s}

= \frac{319}{1000 s}

s im pl i f y (3 x - y)^{2} - (2 x - 3 y)^{2}

s im pl i f y 4 \cdot (2 - 5 x)

f a c t or 9 x^{2} y^{2} - 6 x y - y^{2}

j o in (\frac{x ^{2}}{2}) - (\frac{x}{6})

s im pl i f y \frac{5 m ^{2} + 22 m + 21 - ( 4 m + 10 )}{3}
