Question

Evaluate the radical expression   − 12 \sqrt { - 12 } − 12 ​   without using a calculator. If not possible, state the reason.A)  -12B)  -144C)  144D)  12E) not a real number

Elizabeth Boyle · Accepted Answer

Final Answer : E, Explanation :  The square root of a negative number is not a real number, since the square of any real number is positive. Therefore, $\sqrt{-12}$ is not possible without introducing imaginary numbers.
