I think you mean:
In which case, no this is not a real number because
(141))
so
(141)}\ =\ -i\sqrt{141})
In the future, please use parentheses to make it clear what you are trying to communicate. To the extent that I guessed correctly as to your original meaning, you should have rendered it thus:
-sqrt(-141)
