(i) 5 $x^{3}$ +4 $x^{2}$ +7x

(ii) 3

Open in App

Solution

(i) 5 $x^{3}$ +4 $x^{2}$ +7x

Greatest exponent for variable x is 3. Therefore, 3 is the degree of this polynomial.

(ii)3

3 can also be written as 3 $x^{0}$ . It means that greatest exponent for variable would be 0. Therefore, 0 is the degree of this polynomial.
