$7k^{3}+k^{2}-k+64$

Explicação

The standard form of a polynomial is written with the terms in descending order by degree. That is, the term with the highest degree is written first, followed by the term with the next highest degree, and so on, until the term with the lowest degree (which is usually the constant term) is written last. In this case, the term with the highest degree is $7k^{3}$, followed by $k^{2}$, then $-k$, and finally the constant term $64$. Therefore, the correct standard form of the given polynomial is $7k^{3}+k^{2}-k+64$.
