Question

Which equation illustrates the identity property of multiplication?

A)(a + bi) × c = (ac + bci)
B)(a + bi) × 0 = 0
C)(a + bi) × (c + di) = (c + di) × (a + bi)
D)(a + bi) × 1 = (a + bi)

Answer 1

The multiplicative identity property states that any time you multiply a number by 1, the result, or product, is that original number. D is the correct answer.

Answer 2

The identity property states that when you multiply a number by 1, the result is the original number. Thus, the answer is D.
