整式的除法
(2a^6b³)÷(a³b²)=
(1/48x³y²)÷(1/16x²y)=
(3m²n³)÷(mn)²=
(2x²y)³÷(6x³y²)=
要过程

Answer 1

(2a^6b³)÷(a³b²)=2a^(6-3)b^(3-2）=2a^3b
(1/48x³y²)÷(1/16x²y)=1/3xy
(3m²n³)÷(mn)²=3m²n³÷m²n2=3n
(2x²y)³÷(6x³y²)=8x^6y^3÷(6x³y²)=4/3x^3y

Answer 2

(2a^6b³)÷(a³b²)= (2a^6b³)×(1/a³b²) =2a³b
(1/48x³y²)÷(1/16x²y)=（1/48x³y²)×(16x²y×1)
=1/3xy
(3m²n³)÷(mn)²=(3m²n³)×(1/m²n²)
=3n
(2x²y)³÷(6x³y²)=(8x^6y³)×(1/6x³y²)
=4/3x³y
