+/- 4i

the square root of a number is always plus/minus and the square root of a negative number results in the imaginary number “i”.

Answer:

4 i

Step-by-step explanation:

Negative numbers do not have square roots that are real numbers. Negative number square roots are therefore made up of imaginary numbers that are indicated by the i after the number.
