化简 (6/3)^3

解答

化简

(\frac{6}{3})^{3}

8

求解步骤

(\frac{6}{3})^{3}

使用指数法则:

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

= \frac{6 ^{3}}{3 ^{3}}

6^{3} = 216

= \frac{216}{3 ^{3}}

3^{3} = 27

= \frac{216}{27}

数字相除:

\frac{216}{27} = 8

= 8

- 2 t^{2} - 42 = 48

4 (w + 1) - 7 = 3 (w - 1) + w

3 x^{2} - 2 x - 4 = 0
