Answer 1

a)(7.3^5-3^4+3^6):3^4 (7.(3^5=243)-(3^4=81)+(3^6=729)):(3^4=81)=29

b)(16^3-64^2):8^2 ((16^3=4096)-(64^2=4096)):(8^2=64)=0

c)(3x^2y^2+6y^2):3y lấy 3x^2y^2:3y=x^2y rồi lấy 6y^2:3y=2y cộng 2 kết quả lạ

Answer 2

a)(7.243-81+729):81=29

b)(4096-4096):64=0

c)(9x^2.3x^2y+36y^2):3y=3x^2y+12y

Answer 3

c)\(=\frac{3xy^2+6y^2}{3y}=\frac{3y^2\left(x+2\right)}{3y}=y\left(x+2\right)\)
