Question

What is the degree of the given monomial $3mn$?

Answer 1

Define the degree of the given monomial $3mn$.

Since know that the degree is the term with the greatest exponent, and also to calculate the degree of a monomial with more than one variable for the same term, just sum the exponents for each variable.

A given monomial $3mn$ contains two variables $m\text{and}n$, and the power of both $m\text{and}n$ is $1$. As a result, the monomial $3mn$ degree is:$1+1=2\text{(Adding the exponents of both variables)}$

Hence, the degree of the monomial $3mn$ is $2$.
