Final answer:
The expression -6(3i)(-2i) can be simplified to 18.
Step-by-step explanation:
To simplify the expression -6(3i)(-2i), we can use the rule that multiplying two complex numbers is equivalent to multiplying their magnitudes and adding their angles. First, let's simplify the expression by multiplying the magnitudes: |-6| * |3i| * |-2i| = 6 * 3 * 2 = 36. Next, let's consider the angles: (-6) * (3i) * (-2i) = -18i^2 = -18(-1) = 18. Therefore, the simplified expression is 18.
