Answer:

[tex]3\sqrt{2}[/tex]

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| = [tex]\sqrt{a^2+b^2}[/tex]

-4 -√2i , here a=-4  and b=-sqrt(2)

[tex]|-4-\sqrt{2}i|} =\sqrt{(-4)^2+(-\sqrt{2})^2}[/tex]

= [tex]\sqrt{16+2}[/tex]

= [tex]\sqrt{18}[/tex]

=  [tex]3\sqrt{2}[/tex]
