The monomial degree of 7x.9x^2 is 3
Need to determine monomial degree of 7x.9x^2
That is need to find degree of following monomial 7x.9x^2
Lets first understand what is monomial .
Monomial is a algebraic expression which is having only one term
Degree of monomial is highest power of variable or variables
The degree of the monomial is the sum of the exponents of all included variables
[tex]\text { In our case given monomial is } 7 x .9 x^{2}[/tex]
[tex]7 x .9 x^{2}=7 \times x \times 9 \times x \times x=63 x^{3}[/tex]
Power of x in momomial is 3
hence we can conclude that degree of monomial is 3
