6 (11 + 7)

66 + 42

十进制

14.60477 \dots

求解步骤

6 (11 + 7)

使用分配律:

a (b + c) = ab + a c

6 (11 + 7) = 611 + 67

= 611 + 67

611 = 66

67 = 42

= 66 + 42

e x p an d (6 + 2 i)^{2}

e x p an d (4 - \frac{x}{16})^{6} (x - \frac{1}{x})^{2}

e x p an d \frac{\frac{d}{d x} ( 5 )}{4 ( 3 x ^{2} + 6 x ^{4} + 2 ) ^{3}}

e x p an d (1 + sin (x)) (1 - csc (x))

e x p an d \frac{2 z ^{3} + 6 z ^{2} + 5 z + 1}{z ^{2} ( 2 z + 1 )}
