展开 (16x^2+40x+25)ln(x)

解答

展开

(16 x^{2} + 40 x + 25) ln (x)

16 x^{2} ln (x) + 40 x ln (x) + 25 ln (x)

求解步骤

(16 x^{2} + 40 x + 25) ln (x)

= ln (x) (16 x^{2} + 40 x + 25)

打开括号

= ln (x) \cdot 16 x^{2} + ln (x) \cdot 40 x + ln (x) \cdot 25

= 16 x^{2} ln (x) + 40 x ln (x) + 25 ln (x)

e x p an d \frac{1}{( x - 2 ) ( x + 3 )}

e x p an d \frac{x ^{3}}{( 3 x - 2 ) ^{2}}

e x p an d \frac{( w + 2 ) ( w + 7 )}{( w + 5 ) ( w - 3 )}

e x p an d \frac{2 ( 6 - 1 )}{5}

e x p an d d y + (y cot (g) x - e^{c o s (x)}) d x
