$\text{Degree of Term 1: } 7 \\\text{Degree of Term 2: } 7 \\\text{Degree of Term 3: } 2 \\\text{Degree of Term 4: } 0 \\\text{Degree of the Polynomial: } 7$
$\bf{\text{Solution Outline:}}$ Use the definition of the degree of a term and the definition of the degree of a polynomial for the given polynomial, $\dfrac{5}{7}r^2s^3t^2-\dfrac{3}{8}r^4st^2+\dfrac{4}{9}rs-\dfrac{5}{11} .$ $\bf{\text{Solution Details:}}$ The degree of a term is the sum of the exponents of the variables in the term. Hence, the degree of each term in the given polynomial expression above is \begin{array}{l}\require{cancel} \text{Term 1: } 2+3+2=7 \\\text{Term 2: } 4+1+2=7 \\\text{Term 3: } 1+1=2 \\\text{Term 4: } 0 .\end{array} The degree of a polynomial is the highest degree among all the terms. Hence, the given polynomial has the following characteristics: \begin{array}{l}\require{cancel} \text{Degree of Term 1: } 7 \\\text{Degree of Term 2: } 7 \\\text{Degree of Term 3: } 2 \\\text{Degree of Term 4: } 0 \\\text{Degree of the Polynomial: } 7 .\end{array}
