Find the degree of each algebraic expression
​

Step-by-step explanation:

The degree of an algebraic expression is the largest exponent of the variable present. In expressions with multiple variables, the exponents of each variables are added.

First Expression;

pq: Degree = 1 + 1 = 2

p²q:  Degree = 2 + 1 = 3

p²q²:  Degree = 2 + 2 = 4

The degree of this expression is 4

Second Expression;

2y²z: Degree = 2 + 1 = 3

10yz: Degree = 1 + 1 = 2

The degree of this expression is 3
