Question

Express square root of negative 4 in terms of i

Answer 1

Answer:
`2i, -2i`

Explanation:

To find
`√(-4)`, we want to use imaginary numbers. We need to use imaginary numbers because it is impossible to have two same numbers to multiply to a negative answer. Therefore, we need to use
`i`.

Treat this square as any other square root, but the negative tells us to add an
`i` to the answer.

Square root of 4 is 2 and -2. So our answer will become
`2i, -2i`.
