Answer:
5
Step-by-step explanation:
The given polynomial is
[tex]6x^2+7x^3+8x^5+9[/tex]
Arrange the terms according to the power of variable.
[tex]8x^5+7x^3+6x^2+9[/tex]
In a polynomial the largest exponent of the variable is know as the degree of the polynomial.
In the given polynomial, largest exponent of the variable is 5.
Therefore, the degree of the polynomial is 5.
