化简 2/(m^2p)+5/p

解答

化简

\frac{2}{m ^{2} p} + \frac{5}{p}

\frac{2 + 5 m ^{2}}{m ^{2} p}

求解步骤

\frac{2}{m ^{2} p} + \frac{5}{p}

m^{2} p, p

的最小公倍数:

m^{2} p

根据最小公倍数调整分式

= \frac{2}{m ^{2} p} + \frac{5 m ^{2}}{m ^{2} p}

使用分式法则:

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

= \frac{2 + 5 m ^{2}}{m ^{2} p}

9780 = x (124 - 0.08 x)

310000 > 3 - 9999.9

\frac{5 - x}{2} - \frac{x - 17}{4} \geq \frac{x}{3} - \frac{7 x - 3}{12}

3 (y + 3) + y = 2 (y - 1) + 3

x^{2} + 0 + 1 = 0
