Answer :
We start with the expression
[tex]$$19x^3 + 8x^3.$$[/tex]
Since both terms have the same variable part [tex]$x^3$[/tex], they are like terms. This means we can add their coefficients together:
[tex]$$19 + 8 = 27.$$[/tex]
Thus, the expression simplifies to
[tex]$$27x^3.$$[/tex]
So, the final answer is [tex]$\boxed{27x^3}$[/tex].
