Which property of multiplication is shown below? if x = 3 + 4i and y = 5 + 6i, x × y = y × x.

Commutative property of multiplication

Step-by-step explanation:

According to commutative property of multiplication , for two elements x and y , we have .

Here,

We will also use property :

Also, we know that

Therefore,

So,

On adding real and imaginary parts separately , we get

So, .

Hence, commutative property is verified .

the answer is d. 75%

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
