Monomials are the expressions with one terms.
A.) [tex]-4+6 = 2[/tex]
Since, it has only one term. Therefore, it is a monomial.
B.) [tex]b+2b+2 = 3b+2[/tex]
Since, it has two terms. Therefore, it is not a monomial.
C.) [tex](x-2x)^2 = (-x)^2=x^2[/tex]
Since, it has only one term. Therefore, it is a monomial.
D.) [tex]\frac{rs}{2}[/tex]
Since, it has only one term. Therefore, it is a monomial.
E.) [tex]36x^2yz^3[/tex]
Since, it has only one term. Therefore, it is a monomial.
F.) [tex]a^x[/tex]
Since, the variable is in the power. So it is not a monomial.
G.) [tex]x^\frac{1}{3}[/tex]
Since, the power is not a integer. Therefore, it is not a monomial.
