Sederhanakan bentuk aljabar berikut 1. 18a³b5c6 : 2ab² : 3a²c² 2.(3m–2n)³

1.3a²c²√18a³b⁵c⁶=6ab⁵c⁴
              18a³b⁵c⁶
               ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻ ⁻
                           0

2.(3m-2n)³=3m-2n×(3m-2n)×(3m-2n)
                 =9m²-6mn-6mn+4n²×(3m-2n)
                 =9m²+4n²-12mn×(3m-2n)
                 =27m³-18m²n+12mn²-8n³-36m²n+24mn²
                 =27n³-8n³-54m²n+36mn²
