Answer 1

Step-by-step explanation:

$= > (1 - (1 -(1 - n) {}^{ - 1} ) {}^{ - 1} {)}^{ - 1} \\ \\ = > \bigg(1 - \bigg(1 - \frac{1}{1 - n} \bigg) {}^{ - 1} \bigg) {}^{ - 1} \\ \\ = > \bigg(1 - \bigg( \frac{1 - n - 1}{1 - n} \bigg ) {}^{ - 1} \bigg) {}^{ - 1} \\ \\ = > \bigg(1 - \bigg( \frac{ - n}{1 - n} \bigg ) {}^{ - 1} \bigg) {}^{ - 1} \\ \\ = > \bigg(1 - \bigg( - \frac{1 - n}{n} \bigg) \bigg) {}^{ - 1} \\ \\ = > \bigg( \frac{n+ 1 - n}{n} \bigg) {}^{ - 1} \\ \\ = > ( \frac{1}{n})^{-1}\\\\ => n$
