    \[12a ^{3}b ^{2}\] 12 ---------------- = ---- x \[a ^{3-1} x b ^{2- (-2)}\] \[4ab ^{-2}\] 4

    Sorry it didn't come out right!! Ill do it again We will use the Law \[a ^{m} \div a ^{n} = a ^{m-n}\]

    so it becomes \[12a ^{3}b ^{-2} = 12 a ^{3-1}b ^{2-(-2)}\] ------- ----------- 4ab^-2 4

    Now 12/4 = 3, so final answer is \[3a ^{2}b ^{4}\]
