Answer: There are several expressions that are equivalent to the given expression 3x^2 - 5a^3 + 2y^4. Here are a few examples:
- 2y^4 - 5a^3 + 3x^2
- -5a^3 + 3x^2 + 2y^4
- 3x^2 + 2y^4 - 5a^3
- 2y^4 + 3x^2 - 5a^3
These expressions have the same terms but may differ in the order in which the terms are written. It's important to note that the coefficients and exponents of the variables remain unchanged in each expression.
