Question

Write -(7i)^(2) as either an integer or an integer multiple of i.

Answer 1

`-(7i)^2` simplifies to the integer 49.

To simplify the expression
`-(7i)^2`, we can follow these steps:

Start by simplifying the square of the imaginary number 7i:

`(7i)^2 = 7^2 * (i)^2 = 49 * (-1) = -49`

Finally, add the negative sign to the result:

`-(7i)^2 = -(-49) = 49`
