Answer 2

Answer:

"All the exponents in the algebraic expression must be non-negative integers in order for the algebraic expression to be a polynomial. As a general rule of thumb if an algebraic expression has a radical in it then it isn't a polynomial. Let's also rewrite the third one to see why it isn't a polynomial."
