Question

find the moduls of 1+i÷1-i

​

Answer 1

Answer:

I can't answer it

Explanation:

because moduls is a maths subject

Answer 2

Answer:

$\frac{1 + i}{1 - i} \\ multiply \: \frac{1 + i}{1 + i} \\ \frac{ {(1 + i)}^{2} }{(1 + i)(1 - i)} \\ = \frac{ {1}^{2} + 2(1)(i) + ( {i)}^{2} }{ {1}^{2} - {i}^{2} } \\ = \frac{1 + 2i + ( - 1)}{ {1}^{} - ( - 1)} \\ = \frac{1 + 2i - 1}{1 + 1} \\ = \frac{2i}{2} = i = \sqrt{ - 1 } \\ so \\ \frac{1 + i}{1 - i} = i$
