Final answer:
To find the degree of a mononuclear polynomial, simplify the expression by eliminating terms, identify the highest exponent on the variable, and confirm the degree is reasonable.
Step-by-step explanation:
The degree of a mononuclear polynomial in algebraic expressions is the highest exponent of the variable in the polynomial. To find the degree, you must identify the term with the highest exponent after you have simplified the expression by eliminating terms where possible. Once the polynomial is simplified, the term with the largest exponent on the variable will indicate the degree of the polynomial. It is essential to check the answer to ensure that the resulting degree is reasonable and accurately reflects the simplified algebraic expression.
