Answer:
6. 4y^2 and 7. 27 x^6 y^3
Step-by-step explanation:
6. N/A
________________________________________________
7. Simplify the following:
(3 x^2 y)^3
Multiply each exponent in 3 x^2 y by 3:
3^3 x^(3×2) y^3
3×2 = 6:
3^3 x^6 y^3
3^3 = 3×3^2:
3×3^2 x^6 y^3
3^2 = 9:
3×9 x^6 y^3
3×9 = 27:
Answer: 27 x^6 y^3
