Answer :
To find the degree of the polynomial
[tex]$$9x^8 - 18x^7,$$[/tex]
we follow these steps:
1. Identify the degree (exponent) in each term:
- For the term [tex]$9x^8$[/tex], the degree is [tex]$8$[/tex].
- For the term [tex]$-18x^7$[/tex], the degree is [tex]$7$[/tex].
2. The degree of the polynomial is the highest degree among all terms. Since [tex]$8$[/tex] is greater than [tex]$7$[/tex], the degree of the polynomial is [tex]$8$[/tex].
Thus, the degree of the polynomial is
[tex]$$\boxed{8}.$$[/tex]
