Question

Write the degree of the following polynomial:
(iii) $-8m{n}^6+5m^{3}n$

Answer 1

Step: Find the degree of given polynomial
$-8m{n}^6+5m^{3}n$
The given polynomial consists of two monomials $-8m{n}^6\text{and}5m^{3}n.$
Finding degree of respective monomials:
$-8m{n}^6$ : Degree =1+6=7.
$5m^{3}n$ : Degree =3+1=4.
The highest degree among the monomials is 7.
Hence, the degree of the given polynomial is 7.
