7 (ln (6) + 1)

7 ln (6) + 7

十进制

19.54231 \dots

求解步骤

7 (ln (6) + 1)

使用分配律:

a (b + c) = ab + a c

a = 7, b = ln (6), c = 1

= 7 ln (6) + 7 \cdot 1

数字相乘:

7 \cdot 1 = 7

= 7 ln (6) + 7

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

e x p an d \frac{k}{( J s + b ) ( L s + R ) + k ^{2}}

e x p an d \frac{5}{( s + 5 ) ( s + 7 )}

e x p an d 933 (1 - e^{- 1147 x})

e x p an d \frac{x - 7}{( x - 1 ) ( x + 3 )}
