tolong no.8 dan 9 besok dikumpul

No 9 seharusnya
6xy²/54z
x-nya ketinggalan hehe maaf yaa

8) ( ab² / c ) ÷ ( b / ac )

= ( ab² / c ) × ( ac / b )

= (ab²) × (ac)
-------------------
( c ) × ( b)

= a²b²c
-------------
bc

= (bc) ( a²b)
-----------------
( bc )

= a²b

9) ( x²y³ / 3z ) ÷ ( 18xy / 6 )

= ( x²y³ / 3z ) × ( 6 / 18xy )

= ( x²y³ ) ( 6 )
--------------------
( 3z ) ( 18xy )

= 6x²y³
-----------
54xyz

= (6xy) ( xy²)
--------------------
( 6xy ) ( 9z )

= xy²
--------
9z
