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:
\(-10m^4n^3+8m^2n^6+3m^4n^3-2m^2n^6-6m^2n^6\)
Like terms are those terms which have same variable to the same power.
Combine like terms we have;
\(-7m^4n^3\)
Degree = 4+3 = 7
By definitions:
\(-7m^4n^3\) it is a monomial
Therefore, the simplified polynomial \(-7m^4n^3\) is monomial with degree 7.
