Final answer:
The given expression is a polynomial with terms involving the variables 'a' and 'b'. To simplify the polynomial, combine like terms.
Step-by-step explanation:
The given expression is a polynomial with terms involving the variables 'a' and 'b'.
The polynomial is: -2ab2 + 5ab5 + 7b4 + 8.
To simplify the polynomial, combine like terms.
- The terms -2ab2 and 5ab5 cannot be simplified further as they have different exponents.
- The terms 7b4 and 8 also cannot be combined with the previous terms as they do not involve variables 'a'.
Therefore, the simplified form of the polynomial is -2ab2 + 5ab5 + 7b4 + 8.
