Write the degree of each of the following polynomials:
(i) 2x3 + 5x2 - 7
(ii) 
(iii) 
(iv) 
(v) 
(vi) 5
(vii) 
(i) 2x3 + 5x2 - 7
Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 3.
Therefore degree of the polynomial is 3.
(ii) 
Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 2.
Therefore degree of the polynomial is 2.
(iii) 
Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 2.
Therefore degree of the polynomial is 2.
(iv) 
Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 7.
Therefore degree of the polynomial is 7.
(v) 
Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 3.
Therefore degree of the polynomial is 3.
(vi) 5
Degre is the highest power of the variable of a polynomial. In the given polynomial there is no variable term.
Therefore degree of the polynomial is 0.
(vii) 
Degre is the highest power of the variable of a polynomial. In the given polynomial highest power is 4.
Therefore degree of the polynomial is 4.
