Solution

simplify

(- 1)^{n} (1 - \frac{1}{n})

Solution

\frac{( - 1 ) ^{n} ( n - 1 )}{n}

Solution steps

(- 1)^{n} (1 - \frac{1}{n})

Join

1 - \frac{1}{n} : \frac{n - 1}{n}

= (- 1)^{n} \frac{n - 1}{n}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{( - 1 ) ^{n} ( n - 1 )}{n}
