Answer 1

Answer:

$3\sqrt{2}$

Step-by-step explanation:

We need to find the absolute value of the complex number -4 -√2i

to find absolute value of any complex number we use formula

|a+bi| = $\sqrt{a^2+b^2}$

-4 -√2i , here a=-4  and b=-sqrt(2)

$|-4-\sqrt{2}i|} =\sqrt{(-4)^2+(-\sqrt{2})^2}$

= $\sqrt{16+2}$

= $\sqrt{18}$

=  $3\sqrt{2}$
