For question number ten, the first polynomial is equivalent to 8x^8, the second is 6x^8, the third is 8x^8, and the fourth is 8x^8. So, you should circle the second second term.
For question number 11, the first term is 3^12, the second term is 3^20, the third term is 3^12, and the fourth term is 3^12. So you should circle the second term.
For question number 12, the first term is 49, the second term is 49, and the third term is -49, and the fourth term is -49. So, you should circle the first two or last two.
