kak tolong dibantu ya kak

1. 2/3 X . 1/4 X = 2/12 X² : 1/6 X = 2/12 X² . 6/1 X = 2/2 X = X (disederhanakan)
2. 1/2 X . 1/2 Y
= 1/4 XY . ( 1/4Y / 1/2X ) -1 : ( 2/3X / 1/3Y )
= 1/4 XY . ( 1/4Y / 1/2X ) -1 x ( 1/3Y / 2/3X)
= 1/4 XY . ( 1/12Y² / 2/6X²)-1
= 1/4 XY . (1/12Y² : 2/6X²)-1
= 1/4 XY . ( 1/12Y² x 6/2X²)-1
= 1/4 XY . (1/4X²Y²)-1
= (1/16 X³Y³)-1

saya kira begitu. Maaf kalau ada kesalahan
