Answer 2

Answer

Hi.. Mate ur answer is

(vi) [ 2xy ]³ + [ 3a ]³ = ( 2xy + 3a ) ( 4x²y² - 6axy + 9a² )

(vii) ( x/6 -2y ) ( x²/ 36 + 2xy /6 + 4y ² )

Step-by-step explanation:

6.

8x³y³ = [2xy] ³

27a³= [3a]³

By using the identity X³ + Y ³ = [ X + Y ] [ X² - XY + Y² ]

(2xy )³ + (3a )³ = ( 2xy + 3a ) ( 4x²y² - 6axy + 9a² )

7.

x³/216=( x/6) ³

8y³= (2y)³

By using the identity X ³- Y³ = [ X - Y ] [ X² + XY + Y² ]

( x/6) ³ - (2y)³ = ( x/6 -2y ) ( x²/ 36 + 2xy /6 + 4y ² )
