Final answer:
To break down the expression 270x^3 / (198y^2), divide both the numerator and denominator by their common factor of 9 and then simplify by dividing both by 2.
Step-by-step explanation:
To break down the expression 270x^3 / (198y^2), we can simplify it as follows:
- Divide the numerator and denominator by their common factor, which is 9. This results in 30x^3 / (22y^2).
- Further simplify by dividing both the numerator and the denominator by 2. This gives us the final answer of 15x^3 / (11y^2).
