Here "i" is a symbol called the imaginary number which satisfies the condition  i^2(read as i square)  = -1. I'd suggest you to read more about complex numbers.

Answer 2

$\sf \sqrt{ - 144} = \pm \:12i$

Given :

$\sf \sqrt{ - 144}$

To find :

The value of the expression

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

$\sf \sqrt{ - 144}$

Step 2 of 2 :

Find the value of the expression

$\sf \sqrt{ - 144}$

$\sf = \sqrt{ 144 \times ( - 1)}$

$\sf = \sqrt{ {12}^{2} \times {i}^{2} }$

$\sf = \sqrt{ {(12i)}^{2} }$

$\sf = \pm \: 12i$
