Question

1. What is the degree of the monomial? 4x6

A. 4
B. 10
C. 6
D. 24

2. What is the degree of the monomial? –2

A. –2
B. –3
C. 0
D. –1

3. What is the sum or difference? 5x8 + 9x8

A. 45x8
B. –4x8
C. 14x16
D. 14x8

4. What is the sum or difference? 5y4 – 9y4

A. –45y4
B. 14y4
C. –4y4
D. –4y8

5. Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms. 5x + 2x4 – 4

A. 5x – 4 + 2x4; not a polynomial
B. 2x4 + 5x – 4; fourth-degree

Answer 1

1. the degree is the highest exponent....so answer is 6
2. there is no exponent in this, so the degree is 0
3. 5x^8 + 9x^8 = 14x^8
4. 5y^4 - 9y^4 = - 4y^4
5. 2x^4 + 5x - 4......the degree is 4...and the number of terms is 3...so basically, it is a 4th degree trinomial
