Let's go through each part of the problem:

1. Degree of the term $2x^5$:

   • The degree of a term is the exponent of the variable.
   • For $2x^5$, the exponent of $x$ is 5.
   • Answer: 5

2. Degree of the term $1x^3$:

   • The exponent of $x$ is 3.
   • Answer: 3

3. Degree of the term $3x^6$:

   • The exponent of $x$ is 6.
   • Answer: 6

4. Degree of the term $5$:

   • This is a constant term (there's no variable). The degree of a constant is 0.
   • Answer: 0

5. Degree of the polynomial $2x^5 + 1x^3 + 3x^6 + 5$:

   • The degree of a polynomial is the highest degree of its terms.
   • The highest exponent among the terms is 6 (from $3x^6$).
   • Answer: 6

Here are 5 related questions for practice:

1. What is the degree of the term $-4x^7$?
2. What is the degree of the polynomial $4x^2 + 9x + 7$?
3. What is the degree of a constant term, like $-8$?
4. How would the degree change if there are multiple variables, e.g., $5x^2y^3$?
5. What is the degree of the polynomial $7x^4 - 3x^2 + 2$?

Tip: The degree of a polynomial helps in understanding its behavior for large values of $x$, as the highest degree term dominates.
