what is the sum or difference 4x^10+9x^10
The given expression 4x^10 + 9x^10 consists of two like terms, where both have the same variable 'x' raised to the same power '10'. Therefore, to find the sum or difference, we just need to combine the coefficients of the two like terms, which are 4 and 9. The final expression would be:
Sum: 4x^10 + 9x^10 = 13x^10
Difference: 4x^10 - 9x^10 = -5x^10
So, the sum or difference of 4x^10 and 9x^10 are 13x^10 and -5x^10, respectively.
