化简 11(4cd)(-cd^5)

解答

化简

11 (4 c d) (- c d^{5})

- 44 c^{2} d^{6}

求解步骤

11 (4 c d) (- c d^{5})

使用法则:

a (- b) = - ab

11 (4 c d) (- c d^{5}) = - 11 \cdot 4 c d c d^{5}

= - 11 \cdot 4 c d c d^{5}

数字相乘:

- 11 \cdot 4 = - 44

= - 44 c d c d^{5}

使用指数法则:

aa = a^{2}

cc = c^{2}

= - 44 c^{2} d d^{5}

化简

d d^{5} : d^{6}

= - 44 c^{2} d^{6}

1 - (x + 3) \geq 4 - 2 x

(2 x + 3)^{2} + 8 (2 x + 3) + 11 = 0

f a c t or 15 x^{2} + 14 x - 16

- 4 (x + 5) + 3 x - 1 = - 13 - 13 - 13

- 4 \leq - \frac{2}{3} v + 2
