If you would like to solve (40 * x * 64 * y) / (5 * x * 8 * y), you can calculate this using the following steps:
(40 * x * 64 * y) / (5 * x * 8 * y<span>) = 8 * 8 = 64
</span>
The correct result would be 64.
The answer for the exercise shown above is the option B, which is: 
The explanation is shown below:
To list the powers of the polynomial given in the problem above in descending order, you must write the terms from the highest degree to the lowest degree. You have that the highest degree is

and the lowest degree is

(Because

. Therefore, you have that the correct option is the option B.
