Solution to QOTD 4/3/2020

To solve this, we need to remember that the square root of a negative number is an imaginary number. (no number, multiplied by itself, can result in a negative…) So, this needs to be broken down into parts:

This was our beginning function.
Separate the negative square root.
The square root of 16 is 4, and the square root of -1 is i, (for imaginary).
Multiply 2×4 x i. This is the final solution.

The final answer would be C, by the commutative property.
