 73,200,000 Answer: Problem 3a:  Answer: Problem 4a:  Answer: Problem 5a:  Answer: Since the degree is the sum of the variable exponents and it looks like we have a 2 and a 3 as our exponents, the degree would have to be 2 + 3 = 5.

 Problem 5b:

 -8 Answer: Since this is a constant term, it's degree is 0.

 Problem 6a:  Answer: Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 5. Since there are two terms, this is a binomial.

 Problem 6b:  Answer: Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 3. Since there is one term, this is a monomial.

 Problem 6c:  Answer: Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 2. Since there are two terms, this is a trinomial.
