What is the sum or difference of the following : -. 1. 4x^10-9x^10. 2. 3y^5-10y^5.

We determine the difference or sum of the terms by grouping the terms with the same variables and power. After the terms are grouped, we subtract or add the coefficients of each similar terms. In 1. 4x^10-9x^10; 4-9 is - 5, hence the difference is - 5 x^10. In 2) 3y^5-10y^5; 3-10 = - 7, the answer is - 7y^5.

For the 2 problems, these would be the answers:

For the first equation, 4x^10-9x^10, the answer would be-5x^10. And for the second equation, 3y^5-10y^5, the answer would be - 7y^5. I am hoping that these answers have satisfied your queries about these specific questions.
