Answer:
-4 .
Step-by-step explanation:
Given : [tex]\sqrt{-16}[/tex].
To find : Find the value .
Solution : We have given [tex]\sqrt{-16}[/tex].
We can write the [tex]\sqrt{-16}[/tex] = [tex]\sqrt{- 4 * 4}[/tex].
[tex]\sqrt{-16}[/tex] = -4 .
By the radical rule : [tex]\sqrt{-a *a} =-a[/tex].
Here, a = 4.
So, [tex]\sqrt{-16}[/tex] = -4 .
Therefore, -4 .
