展开 ln(x)(x+2)(x+8)

解答

展开

ln (x) (x + 2) (x + 8)

x^{2} ln (x) + 10 x ln (x) + 16 ln (x)

求解步骤

ln (x) (x + 2) (x + 8)

乘开

(x + 2) (x + 8) : x^{2} + 10 x + 16

= ln (x) (x^{2} + 10 x + 16)

乘开

ln (x) (x^{2} + 10 x + 16) : x^{2} ln (x) + 10 x ln (x) + 16 ln (x)

= x^{2} ln (x) + 10 x ln (x) + 16 ln (x)
