Explanation
| $$ \begin{aligned}5a^4+7a^3+8a^4+a^3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}13a^4+8a^3\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{5a^4} + \color{red}{7a^3} + \color{blue}{8a^4} + \color{red}{a^3} = \color{blue}{13a^4} + \color{red}{8a^3} $$ |
