Question

I was wondering what the answer of |1-i| is.

Answer 1

Answer:

$\sqrt{2}$ which is also 1.4142

Step-by-step explanation:

To solve this the formula is...

| a+(b)i | = $\sqrt{(a+(b)i)(a-(b)i)}$ which equals... $\sqrt{a^2+b^2}$

From the equation we know that a=1 and b=-1 because the "i" is negative

Plug in numbers... $\sqrt{1^2+(-1)^2}$

Solve... you would get $\sqrt{1+1}$

This equals $\sqrt{2}$

Hope this helps!
