Final answer:
The difference between 3x² and 4y⁵ is written in algebraic form as 3x² - 4y⁵.
Step-by-step explanation:
The expression that represents the difference between 3x² and 4y⁵ is 3x² - 4y⁵.
When we talk about the difference between two terms in mathematics, we are referring to the subtraction operation. This means we subtract the second term from the first. The term '3x²' refers to the integer power of x raised to the power of 2, which can be thought of as x multiplied by itself, and similarly, '4y⁵' is y raised to the power of 5, which is y multiplied by itself five times. Therefore, the expression 3x² - 4y⁵ shows that we are subtracting the second term from the first.
