Q3 of 105 Page 279

Workout the following divisions:

11a3b3(7c – 35) ÷ 3a2b2(c – 5)

In the given term


Dividend = 11a3b3(7c – 35) ÷ 3a2b2(c – 5)


Take out the common part in binomial term


= 11 × a × a × a × b × b × b (7 × c - 5 × 7 )


= 11 × a × a × a × b × b × b × 7 (c - 5 )


= 77a3b3(c - 5)


Divisor = 3a2b2(c – 5)


=


= ab


Hence dividing 11a3b3(7c – 35) by 3a2b2(c – 5) gives out ab
