Jawab:

Penjelasan dengan langkah-langkah:

1) 4a/3x – 4/2x

= (4a × 2)/(3x × 2) – (4 × 3)/(2x × 3)

= 8a/6x – 12/6x

= 8a-12/6x

2) 2a/3x × 2x-6/12

= 2a(2x – 6)/(3x × 12)

= 2a(2x – 6)/36x

= 4ax-12a/36x

= ax-12a/36

= ax-3a/9

3) xy/z ÷ x/yz

= x¹y¹/z¹ ÷ x¹/y¹z¹

= x¹y¹/z¹ × y¹z¹/x¹

= x¹y^(1 + 1)z¹/z¹x¹

= x¹y²z¹/z¹x¹

= y²
