${(x - 1)}^{\frac{2}{3}} + {(x - 1)}^{\frac{1}{3}}$

解题步骤 1

从 ${(x - 1)}^{\frac{2}{3}}$ 中分解出因数 ${(x - 1)}^{\frac{1}{3}}$ 。

${(x - 1)}^{\frac{1}{3}} {(x - 1)}^{\frac{1}{3}} + {(x - 1)}^{\frac{1}{3}}$

解题步骤 2

乘以 $1$ 。

${(x - 1)}^{\frac{1}{3}} {(x - 1)}^{\frac{1}{3}} + {(x - 1)}^{\frac{1}{3}} \cdot 1$

解题步骤 3

从 ${(x - 1)}^{\frac{1}{3}} {(x - 1)}^{\frac{1}{3}} + {(x - 1)}^{\frac{1}{3}} \cdot 1$ 中分解出因数 ${(x - 1)}^{\frac{1}{3}}$ 。

${(x - 1)}^{\frac{1}{3}} ({(x - 1)}^{\frac{1}{3}} + 1)$
