Answer:
Step-by-step explanation:
Remark
√-12
The square root of -12 must have an i in it somewhere. If it does not, then the minus sign stays under the root sign. If you take the root of -1 you get i, and that is outside √ sign.
Solution
A is incorrect. i is on the outside of the root sign.
B is the answer.
C does not seem to take the square root of anything except -1 so it is incorrect.
D Has no i anywhere and the -1 is incorrectly placed. D is wrong
E is just wrong. The minus should disappear once the square root of -1 is taken. 12 has a root that has not been declared.
