I dont understand the question
To find mean all you have to do is add all the numbers up and divide ny how many numbers there are. If you add them all together is equals 1295. now divide that number by the amount of numbers there are which is 10, and divide 1295 by 10. You get 129.5
The answer is 6 because you do this
1/3 of 18 divide 18 by 3 amd get 6
178.
If number CLXXVIII is within to text or sentence it should be read in its equivalent in arabic numbers, in this case 178.

If I got it correctly, the question is what is 24x^2y^6-16x^6y^2+4xy^2 divided by 4xy^2 and the answer is 6xy^4-4x^5+1.
