Multiplying and Simplifying Imaginary Numbers

Using the imaginary unit i, simplify the expression: 3i * 5i

• 8i

• -15i

• 20

• -15

Using the imaginary unit i, simplify the expression: 2i * (4i + 3)

• 6i^2 + 8i = -6 + 8i

• 8i^2 + 6i = -8 + 6i

• 16i^2 + 12i = -16 + 12i

• 8i^2 + 3 = -8 + 3i

Using the imaginary unit i, simplify the expression: (6i - 2) * (3i + 1)

• -12 + 18

• -12 + 18i

• 12 - 18i

• -12 - 18i

Using the imaginary unit i, simplify the expression: (5i + 2) * (4i - 3)

• 3 + 6i

• -8 - 15i

• -14 + 17i

• 10 - 7i
