Which statement is true about the polynomial
–10m4n3 + 8m2n6 + 3m4n3 – 2m2n6 – 6m2n6 after it has been fully simplified?

the simplified version is -7m^4n^3, assuming the numbers after m and n are supposed to be exponents.

(a monomial with a degree of 7).

Step-by-step explanation:

The polynomial  consists of 5 monomials of form  and

To simplify this polynomial, group terms that are of the same form:

1.-10m^4n^3+ 3m^4n^3=m^4n^3(-10+3)=-7m^4n^3.

2.8m^2n^6-2m^2n^6-6m^2n^6=m^2n^6(8-6-2)=m^2n^6\cdot 0=0.

Then the simpliest form of the polynomial  is  You can see that only one monomial left and this monomial has a degree of 4+3=7.
