(2 - 3) 3 π

6 π - 33 π

十进制

2.52536 \dots

求解步骤

(2 - 3) \cdot 3 π

= 3 π (2 - 3)

使用分配律:

a (b - c) = ab - a c

a = 3 π, b = 2, c = 3

= 3 π 2 - 3 π 3

= 3 \cdot 2 π - 33 π

数字相乘:

3 \cdot 2 = 6

= 6 π - 33 π

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

e x p an d 2 \cdot sin (x) (x - 6 y)

e x p an d (0.5 + (0.5 \cdot cos^{2} (x)))^{2}

e x p an d (9 (x + 3)^{2} - 4 (y - 4)^{2} = - 96) (- \frac{1}{96})
