Question

Write the degree of the polynomial for each of the following. 

i. 5 + 3x⁴ 

ii. 7 

iii. ax⁷ + bx⁹ (a, b are constants)

Answer 1

i. 5 + 3x⁴ 

Here, the highest power of x is 4. 

∴ Degree of the polynomial = 4 

ii. 7 = 7x° 

∴ Degree of the polynomial = 0 

iii. ax⁷ + bx⁹ 

Here, the highest power of x is 9. 

∴ Degree of the polynomial = 9
