Find the degree of the polynomial and determine whether monomial. Binomial. Trinomial or none of these

ANSWER :
4
none of these
EXPLANATION :
From the problem, we have :
[tex]7m^4-3m^3+5m-8[/tex]The degree of the polynomial is the highest exponent.
In this case, the highest exponent is 4.
So the degree is 4
The polynomial has 4 terms, so it cannot be a monomial, binomial or trinomial.
So none of these
