1. The problem is to provide 3 examples of monomials. 2. A monomial is an algebraic expression consisting of only one term, which is a product of numbers and variables with non-negative integer exponents. 3. Examples of monomials include: - $5x^3$ (a coefficient 5 multiplied by variable $x$ raised to the power 3) - $-2y$ (a coefficient -2 multiplied by variable $y$ to the power 1) - $7$ (a constant, which is also a monomial with no variable) 4. These are all single terms without addition or subtraction between variables, fitting the definition of monomials.
