Answer:

1-4i

Step-by-step explanation:

[tex]i=\sqrt{-1}[/tex]

We have [tex]1-\sqrt{-16}[/tex].

Let's look at the [tex]\sqrt{-16}[/tex] part.

Since it has a negative inside the square root, it is imaginary.  This is our imaginary unit [tex]i=\sqrt{-1}[/tex].

So [tex]\sqrt{-16}[/tex]

[tex]=\sqrt{16} i [/tex]

[tex]=4i[/tex]

So [tex]1-\sqrt{-16}=1-4i[/tex]
