Is $7{x}^{3}$ a monomial?

Expert

Explanation:
A monomial is a product of a constant and variables raised to non-negative whole number powers.
Monomial Examples:
$5x,\frac{2}{3}{a}^{2},4{x}^{3}{y}^{2}z$
Examples that may take some thought:
3, (Sometimes we say that this is $3{x}^{0}$, since ${x}^{0}=1$ for all x except x =0)
0, (sometimes it is helpful to write this as $0{x}^{2}$ or 0t)
$7\sqrt{3}{x}^{5}$, (It is ok for the constant to involve a root)
Not Monomials:
$\frac{2}{x}$ (Monomials do not have variables in the denominator.)
$5\sqrt{x}$ (Monomials do not have roots of the variables.)
$3{x}^{2}+7x$ (This is a binomial.)
