化简 (2u^2v^3)^3(3u^{-3}v)^2

解答

化简

(2 u^{2} v^{3})^{3} (3 u^{- 3} v)^{2}

解答

72 v^{11}

求解步骤

(2 u^{2} v^{3})^{3} (3 u^{- 3} v)^{2}

化简

(2 u^{2} v^{3})^{3} : 8 u^{6} v^{9}

= 8 u^{6} v^{9} (3 u^{- 3} v)^{2}

化简

(3 u^{- 3} v)^{2} : \frac{9 v ^{2}}{u ^{6}}

= 8 u^{6} v^{9} \frac{9 v ^{2}}{u ^{6}}

交叉约去公约数:

u^{6}

= 8 v^{9} \cdot 9 v^{2}

数字相乘:

8 \cdot 9 = 72

= 72 v^{9} v^{2}

使用指数法则:

a^{b} \cdot a^{c} = a^{b + c}

v^{9} v^{2} = v^{9 + 2}

= 72 v^{9 + 2}

数字相加:

9 + 2 = 11

= 72 v^{11}

流行的例子

化简 (sqrt(2))/2+(1-sqrt(2))/(-1)

s im pl i f y \frac{2}{2} + \frac{1 - 2}{- 1}

因式分解-25a^2+185a-70

f a c t or - 25 a^{2} + 185 a - 70

1/4 x-1/5 x+1/20 x=4

\frac{1}{4} x - \frac{1}{5} x + \frac{1}{20} x = 4

4 - c = 5

\frac{3}{4} = \frac{x}{20}
