Given:

Consider the expression is
√(-12).

To find:

The value of given expression.

Solution:

We have,


√(-12)

It can be written as


√(-12)=√(-1* 12)


√(-12)=√(-1)* √(12)
[\because √(ab)=√(a)√(b)]


√(-12)=i* √(12)
[\because √(-1)=i]


√(-12)=√(12)i

Therefore, the value of given expression is
√(12)i.

Note: all options are incorrect.
