radical 6^{2/3}

解答

exponent to radical

6^{\frac{2}{3}}

3 6^{2}

十进制

3.30192 \dots

求解步骤

6^{\frac{2}{3}}

\frac{2}{3} = 2 \cdot \frac{1}{3}

= 6^{2 \cdot \frac{1}{3}}

使用指数法则:

a^{b c} = (a^{b})^{c}, a \geq 0

6^{2 \cdot \frac{1}{3}} = (6^{2})^{\frac{1}{3}}

= (6^{2})^{\frac{1}{3}}

使用指数法则:

a^{\frac{1}{n}} = n a

(6^{2})^{\frac{1}{3}} = 3 6^{2}

= 3 6^{2}

so l v e f or x, 8 x - 11 = 3 x - 13

so l v e f or y, 6 = 2 (y + 2)

f a c t or 4 x^{3} + x^{2} - 8 x - 2

so l v e f or x, 3 x^{2} + 5 x = 2
