化简 (4/9)^{3/2}

解答

化简

(\frac{4}{9})^{\frac{3}{2}}

\frac{8}{27}

十进制

0.29629 \dots

求解步骤

(\frac{4}{9})^{\frac{3}{2}}

使用指数法则:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{4 ^{\frac{3}{2}}}{9 ^{\frac{3}{2}}}

4^{\frac{3}{2}} = 8

= \frac{8}{9 ^{\frac{3}{2}}}

9^{\frac{3}{2}} = 27

= \frac{8}{27}

4 x + 3 x - 7 = 60 - 2 x - 13

7 (y + 4.5) = 32.5
