化简 (654*3)/(6^5)

解答

化简

\frac{6 \cdot 5 \cdot 4 \cdot 3}{6 ^{5}}

解答

\frac{5}{108}

+1

十进制

0.04629 \dots

求解步骤

\frac{6 \cdot 5 \cdot 4 \cdot 3}{6 ^{5}}

\frac{6}{6 ^{5}} = \frac{1}{6 ^{4}}

= \frac{5 \cdot 4 \cdot 3}{6 ^{4}}

因式分解数字:

4 = 2^{2}

= \frac{5 \cdot 2 ^{2} \cdot 3}{6 ^{4}}

因式分解

6^{4} : 2^{4} \cdot 3^{4}

= \frac{5 \cdot 2 ^{2} \cdot 3}{2 ^{4} \cdot 3 ^{4}}

\frac{2 ^{2}}{2 ^{4}} = \frac{1}{2 ^{2}}

= \frac{5 \cdot 3}{2 ^{2} \cdot 3 ^{4}}

\frac{3}{3 ^{4}} = \frac{1}{3 ^{3}}

= \frac{5}{2 ^{2} \cdot 3 ^{3}}

2^{2} \cdot 3^{3} = 108

= \frac{5}{108}

流行的例子

4 - 3 x \leq - (1 + 8 x)

∣ x ∣ = \frac{1}{3}

5 x + 12 = 2 (2 x + 7)

3 x^{2} + 2 x^{2} = 35

因式分解 9xy^2-4x

f a c t or 9 x y^{2} - 4 x
