Notes:For example, if this is the problem

and all you have is an answer,

= you will only get credit if you can prove you're a mathematical genius who can skip the three steps in between and mentally produce the solution.

Regarding class work:

If you use a calculator, write down whatever you are entering.

A. Don't waste your time for no credit....B. Especially when most of the copied answers are incorrect anyway.

Summary:

Practice Problem Section of Notebook, pls.

Khan Academy Practice:

The degree of a monomial is defined as the sum of all the exponents of the variables, including the exponents of 1.

Finding the Degree of a MonomialMonomials & Polynomials are often classified by their degree.The degrees of a polynomial determines how it is written.

Find the Degree of each Monomial
