化简 (P+(n^2a)/(v^2))(v-nb)

解答

化简

(P + \frac{n ^{2} a}{v ^{2}}) (v - nb)

\frac{( P v ^{2} + n ^{2} a ) ( v - nb )}{v ^{2}}

求解步骤

(P + \frac{n ^{2} a}{v ^{2}}) (v - nb)

合并

P + \frac{n ^{2} a}{v ^{2}} : \frac{P v ^{2} + n ^{2} a}{v ^{2}}

= \frac{P v ^{2} + n ^{2} a}{v ^{2}} (v - nb)

使用分式法则:

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

= \frac{( P v ^{2} + n ^{2} a ) ( v - nb )}{v ^{2}}

e x p an d \frac{5}{( x + 4 ) ^{2}}

e x p an d 2 (6 - \frac{4}{3}) π

e x p an d u (2, 0) v (3, - 4)

e x p an d \frac{x}{( 2 x + 1 ) ^{2}}

e x p an d \frac{s + 2}{( s + 3 ) ( s + 4 )}
