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
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
