Answer:
Degree of the polymonial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.
Step-by-step explanation:
I think the equation is 4m² – 3[tex]m^{6}- 5m^{4}[/tex]
Therefore, degree of the polynomial is the sum of the powers of the variables,
2 + 6 + 4 = 12
Hope this helps!
