Answer: The correct classification of 2x4 - 8x5 - 2x2 + 5 is 5th-degree polynomial.
We know that the highest exponent of a polynomial is called the degree of the polynomial.
The highest degree of the given polynomial is 5. Hence, from the above-written concepts, we can say that the degree of the polynomial is 5.
Thus, the polynomial is a 5th-degree polynomial.
