Step-by-step explanation:

Polynomial       4x¹⁰ + 9x¹⁰

To sum or subtract polynomials, just look for like terms and do the operations considering the rules of signs.

In this problem both terms are like terms, then we add the coefficients and write the variable without a change.

                         4x¹⁰ + 9x¹⁰  = 13x¹⁰
