2 (3 - 1)

6 - 2

十进制

1.03527 \dots

求解步骤

2 (3 - 1)

使用分配律:

a (b - c) = ab - a c

2 (3 - 1) = 23 - 2 \cdot 1

= 23 - 2 \cdot 1

23 - 2 \cdot 1 = 6 - 2

= 6 - 2

e x p an d (\frac{1}{y ^{2}}, - \frac{2 x}{y ^{3}}) \cdot (1, 0)

\frac{d}{d v} ((p) (p + \frac{5.2}{v ^{2}}) (v - 8.1))

e x p an d x^{2} (\frac{x ^{3} ln ( x )}{3} - \frac{x ^{3}}{9})

e x p an d (x - 4) (a + 3 x + 1) (x + 1)

e x p an d (2 x - 3) e^{x^{4}} + e^{x^{4}} \cdot 4 x^{3} (x^{2} - 3 x)
