Answer:
true
Step-by-step explanation:
because the expression shown is a monomial we simply add the degrees of each term
4 + 2 + 3 = 9
5x4y2z3 indeed has a degree of 9
Note: if the terms were being added we take the highest degree and that is the degree of the expression.
ex. 5x^4 + y^2 + z^3 would have a degree of 4
