Question 1177517

{{{4a^3b - 2a^2b^3 + 8ab^3 + 2a^2b^3 - 7}}}

{{{4a^3b  + 8ab^3 + cross(2a^2b^3)- cross(2a^2b^3) - 7}}}

{{{4a^3b  + 8ab^3  - 7}}}

The degree of each term is the sum of the exponents on the variables.

{{{a^3b^1}}}->{{{3+1=4}}}
or
{{{a^1b^3}}}->{{{1+3=4}}}


so, the degree of {{{4a^3b  + 8ab^3  - 7}}} is {{{4}}}
