Question

the smallest positive integer n for which (1+i / 1-i) whole raised to n =1 is (ans 4 )plzzzz say how asap?

Answer 1

${( \frac{1 + i}{1 - i} )}^{n} = 1$
$\sqrt[n]{ { \frac{1 + i}{1 - i} }^{n} } = \sqrt[n]{1}$
$\frac{1 + i}{1 - i} = 1$
$1 + i = 1 - i$
$2i = 0$
$i = 0$

Answer 2

the answer to this question is 0.
