Answer 2

The expression you provided is:

15x^4y^3 - 5x^2y^2 + 10x^2y

This expression consists of several terms involving variables x and y raised to different powers. Let's break it down:

Term 1: 15x^4y^3 This term has x raised to the power of 4 and y raised to the power of 3. The coefficient of this term is 15.

Term 2: -5x^2y^2 This term has x raised to the power of 2 and y raised to the power of 2. The coefficient of this term is -5.

Term 3: 10x^2y This term has x raised to the power of 2 and y raised to the power of 1. The coefficient of this term is 10.

These terms represent different monomials, which are algebraic expressions with a single term. The exponents indicate the powers to which x and y are raised, while the coefficients are the numerical constants multiplying each monomial.
