## Which property of multiplication is shown below? if x = a + bi and y = c + di, x × y = y × x. commutative property identity property

The option A. is correct

Step-by-step explanation:

x = a + bi and y = c + di

Now, x × y = (a + bi) × (c + di)

= ac + adi + bci + bdi²

= ac – bd + i(ad + bc)

Now, y × x = (c+ di) × (a + bi)

= ac + bci + adi + bdi²

= ac – bd + i(ad + bc)

Therefore, x × y = y × x

And if ab = ba then the property is known as commutative property.

Hence, The option A. is correct
