(5 x + 3) d e

5 d e x + 3 d e

求解步骤

(5 x + 3) d e

= d e (5 x + 3)

使用分配律:

a (b + c) = ab + a c

a = d e, b = 5 x, c = 3

= d e \cdot 5 x + d e \cdot 3

= 5 d e x + 3 d e

\frac{d}{d t} ((s) (\frac{3}{4 π} cos (4 t) + \frac{3}{7 π} sin (7 t)))

e x p an d \frac{1}{2 ( x + 7 )}

e x p an d - 5 (\frac{- 5 - 3 y}{10} - 4 y = 10)

e x p an d \frac{1}{( s ^{3} ( s ^{2} + w ^{2} ) )}

e x p an d \frac{0.114 + x}{( 1.448 - 2 x ) ^{2}}
