Final answer:
To simplify (x^2y)^3, we need to raise each term inside the parentheses to the power of 3. This means we multiply the exponents of x and y by 3. So, the correct simplified expression is x^6y^3.
Step-by-step explanation:
To simplify (x2y)3, we need to raise each term inside the parentheses to the power of 3. This means we multiply the exponents of x and y by 3. So, we get x2*3y1*3 which simplifies to x6y3. Therefore, the correct simplified expression is x6y3.
