What is the principal square root of -4
devlian [24]

Answer:

The principal square root of -4 is 2i.

Step-by-step explanation:

\sqrt{-4} = 2i

We have the following steps to get the answer:

Applying radical rule \sqrt{-a} =\sqrt{-1} \sqrt{a}

We get \sqrt{-4} =\sqrt{-1} \sqrt{4}

As per imaginary rule we know that \sqrt{-1}=i

= \sqrt{4} i

Now \sqrt{4} =2

Hence, the answer is 2i.
