1) 18a⁴b
-------------
3a³b

= 3a³b ( 6a)
-------------------
3a³b

= 6a

4) - 32p^7 q^8 r⁴
--------------------------
8 pq^6 r

= 8pq^6 r ( - 4p^6 q² r³)
------------------------------------
8pq^6 r

= - 4p^6 q² r³


7) 56x^7 y^6
--------------------
( - 4x⁴y^5 ÷ 2x²y⁴)

= 56x^7 y^6
-------------------
- 2x²y

= - 2x²y ( - 28x^5 y^5 )
-----------------------------------
- 2x²y

= - 28x^5 y^5


10) a^9 b^8
--------------------------
a³b × ( - a²b⁴ )

= a^9 b^8
-----------------
- a^5 b^5

= - a^5 b^5 ( - a⁴ b³)
------------------------------
- a^5 b^5

= - a⁴b³


13) 48x^5 y^8
------------------------
6x³y^5 ÷ 3x²y²

= 48x^5 y^8
-----------------------
2xy³

= 2xy³ ( 24x⁴ y^5)
----------------------------
2xy³

= 24x⁴ y^5
