Work Step by Step

We are given the expression: $(5r^3+8)+(6r^3+3)$. Use the distributive property and remove parentheses. We have: $5r^3+8+6r^3+3$. Combine the terms having the same degree using the commutative property: $(5r^3+6r^3)+(8+3)$. Simplify by adding the terms of the same degree: $11r^3+11$ which is final answer.
