展开 (ln(x)+1)(2)

解答

展开

(ln (x) + 1) (2)

2 ln (x) + 2

求解步骤

(ln (x) + 1) (2)

= (2) (ln (x) + 1)

使用分配律:

a (b + c) = ab + a c

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

= (2) ln (x) + (2) \cdot 1

化简

(2) ln (x) + (2) \cdot 1 : 2 ln (x) + 2

= 2 ln (x) + 2

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

e x p an d 4 a^{2} - 2 (2 b)^{3} + ab (a = - 1, b = 2)

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

e x p an d a^{(2 n + 1) (2 n - 1)}

e x p an d 100 (X - 16 = 8192)
