Question

Evaluate expression -16 squared and write the result in form a + bi

Answer 1

Writing it in the form of a+bi we get 0+4i

Step-by-step explanation:

We need to evaluate expression -16 squared and write the result in form a+bi

The given expression is: $\sqrt{-16}$

We know that $\sqrt{-1}=i$

We know that 16= 4x4 = 4^2

Putting values:

$\sqrt{-16}=\sqrt{-1}\sqrt{16}\\=\sqrt{4^2}i\\=4i$

So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i
