(6 x + 5) e^{2 x}

6 e^{2 x} x + 5 e^{2 x}

求解步骤

(6 x + 5) e^{2 x}

= e^{2 x} (6 x + 5)

使用分配律:

a (b + c) = ab + a c

a = e^{2 x}, b = 6 x, c = 5

= e^{2 x} \cdot 6 x + e^{2 x} \cdot 5

= 6 e^{2 x} x + 5 e^{2 x}

e x p an d \frac{1 0 ^{5}}{1 0 ^{3}}

e x p an d e^{x} (1 + x)^{17}

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

e x p an d \frac{( n + 1 ) ( n ^{3} + 1 )}{n ^{4}}

e x p an d \frac{4}{s ^{2} ( s + 1 ) ( s + 2 )}
