Question
Answer
$$8k^4+3k^3+k^3-8k^4=4k^3$$
Explanation
| $$ \begin{aligned}8k^4+3k^3+k^3-8k^4& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}4k^3\end{aligned} $$ | |
| ① | Combine like terms: $$ \, \color{blue}{ \cancel{8k^4}} \,+ \color{green}{3k^3} + \color{green}{k^3} \, \color{blue}{ -\cancel{8k^4}} \, = \color{green}{4k^3} $$ |
