Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Fully simplify the expression. (4i)(-i)
To simplify the expression (4i)(-i), we can use the rule that says i^2 = -1.
First, we multiply the coefficients: 4 * (-1) = -4.
Next, we multiply the imaginary parts: i * i = i^2 = -1.
Finally, we combine the results: (-4)(-1) = 4.
So, the simplified expression is 4.
