4a%5E3b+-+2a%5E2b%5E3+%2B+8ab%5E3+%2B+2a%5E2b%5E3+-+7
4a%5E3b++%2B+8ab%5E3+%2B+cross%282a%5E2b%5E3%29-+cross%282a%5E2b%5E3%29+-+7
4a%5E3b++%2B+8ab%5E3++-+7
The degree of each term is the sum of the exponents on the variables.
a%5E3b%5E1->3%2B1=4
or
a%5E1b%5E3->1%2B3=4

so, the degree of 4a%5E3b++%2B+8ab%5E3++-+7 is 4
