Ta có :

( - 2 ) . ( -2 ) . ( -2 ) . ( - 3 ) . ( - 3 ) . ( -3 )

= ( - 2 )³ . ( - 3 )³ 

= [ ( - 2 ) . ( -3 ) ]³ 

= 6 ³

(-2)³x(-3)³

(-2) . (-2) . (-2) . (-3) . (-3) . (-3) = (-2)³ . (-3)³

Bạn tick cho mình nha!!!

 2 x 2 x 3 x 3 x 3 x 6

=\(2^2.3^3.6\)

Dấu"." là dấu nhân nhé

2 x 2 x 3 x 3 x 3 x 6 

= \(2^2.3^3.6\)

= 648
