a) ( 4x²y³) • ( 16x⁴ )
----------------------------
( 2x³ ) • ( 8y³ )

= ( 4y³ )( x² ) • ( 2x³ )( 8x )
--------------------------------------
( 4y³ )( 2 ) • ( 2x³ )

= ( x² ) • ( 8x )
-----------------------
( 2 )

= 8x³
---------
2

= 4x³


b) ( 35a³b ) • ( 22b⁴ )
--------------------------------
( 6b^7 ) • ( 55a^5 b )

= ( 5a³b )( 7 ) • ( 2b⁴ )( 11 )
--------------------------------------
( 5a³b )( 11a² ) • ( 2b⁴ )( 3b³ )

= ( 7 ) • ( 11 )
--------------------
( 11a² ) • ( 3b³ )

= 7
-----------
3a²b³


c) ( 5xy³ ) • ( 6x²y )
-----------------------------
( 7x³y ) • ( 30x⁴y )

= ( 5y² ) • ( 1 )
-----------------------
( 7x² ) • ( 5x² )

= y²
-----------
7x⁴

d) ( 14m⁴n² ) • ( m² )
------------------------------
( 42mn^5 ) • ( 7m^5 )

= ( m³ ) • ( 1 )
--------------------
( 3n³ ) • ( 7m³ )

= 1
---------
21n³


e) 4x ( 2x - 30 ) • ( x - 1 )
------------------------------------
( x - 1 ) • ( 8x² )

= 2x - 30
--------------
2x

= 2 ( x - 15 )
------------------
2x

= x - 15
-------------
x


f) ( 13ab² ) • ( 2x - 3 )
---------------------------------------
2a⁴ ( 3 - 2x ) • ( 26a⁴ )

= ( b²) • ( 2x - 3 )
---------------------------------
- 2a⁴ ( 2x - 3 ) • ( 2a³ )

= b²
----------
- 4a^7
