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 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
