36 (π - 2)

36 π - 72

十进制

41.09733 \dots

求解步骤

36 (π - 2)

使用分配律:

a (b - c) = ab - a c

a = 36, b = π, c = 2

= 36 π - 36 \cdot 2

数字相乘:

36 \cdot 2 = 72

= 36 π - 72

e x p an d \frac{( x ^{2} - 2 x - 15 ) ( x + 3 )}{( - x ^{2} - 1 ) ( x - 2 )}

e x p an d l im x \Rightarrow - 2 (x^{2} - x - 6)

e x p an d t e^{4 t} f (t - 3) H (t - 3)

e x p an d e^{2 (s i n (t) + 1)}

e x p an d \frac{3}{5 ( 2 x - 4 ) ^{2}}
