(i) 5x3+4x2+7x
Solution:
The highest power of the variable in a polynomial is the degree of the polynomial.
Here, 5x3+4x2+7x = 5x3+4x2+7x1
The powers of the variable x are: 3, 2, 1
the degree of 5x3+4x2+7x is 3 as 3 is the highest power of x in the equation.
(ii) 4–y2
Solution:
The highest power of the variable in a polynomial is the degree of the polynomial.
Here, in 4–y2,
The power of the variable y is 2
the degree of 4–y2 is 2 as 2 is the highest power of y in the equation.
(iii) 5t–√7
Solution:
The highest power of the variable in a polynomial is the degree of the polynomial.
Here, in 5t–√7 ,
The power of the variable t is: 1
the degree of 5t–√7 is 1 as 1 is the highest power of y in the equation.
(iv) 3
Solution:
The highest power of the variable in a polynomial is the degree of the polynomial.
Here, 3 = 3×1 = 3× x0
The power of the variable here is: 0
the degree of 3 is 0.
