It is a monomial with a degree of 7.

Answer:

Option B is correct.

it is a monomial with a degree of 7

Step-by-step explanation:

Monomial is an expression that contains one term

For example: 2ab

Degree: The sum of the exponent of the variables

Given the Polynomial:

[tex]-10m^4n^3+8m^2n^6+3m^4n^3-2m^2n^6-6m^2n^6[/tex]

Like terms are those terms which have same variable to the same power.

Combine like terms we have;

[tex]-7m^4n^3[/tex]

Degree = 4+3 = 7

By definitions:

[tex]-7m^4n^3[/tex] it is a monomial

Therefore, the simplified polynomial  [tex]-7m^4n^3[/tex] is monomial with degree 7.
