展开 (2x-1)*(ln(5))

解答

展开

(2 x - 1) \cdot (ln (5))

2 ln (5) x - ln (5)

求解步骤

(2 x - 1) (ln (5))

= (ln (5)) (2 x - 1)

使用分配律:

a (b - c) = ab - a c

a = (ln (5)), b = 2 x, c = 1

= (ln (5)) \cdot 2 x - (ln (5)) \cdot 1

= 2 (ln (5)) x - 1 \cdot (ln (5))

化简

2 (ln (5)) x - 1 \cdot (ln (5)) : 2 ln (5) x - ln (5)

= 2 ln (5) x - ln (5)
