Find the product of the following pairs of monomials.

(i) 4, 7p

(ii) – 4p, 7p

(iii) – 4p, 7pq

(iv) 4p

(v) 4p, 0

- 4 x 7 p = 28p
- - 4p x 7p = -28p
^{2} - - 4p x 7pq = -28p
^{2}q - 4p
^{3}x - 3p = -12p^{4} - 4p x 0 = 0

Find the areas of rectangles with the following pairs of monomials as their lengths and breadths respectively.

- (p, q)
- (10m, 5n)
- (20x
^{2}5y^{2}) - (4x, 3x
^{2})\ - (3mn, 4np)

Area of rectangle = Length x breadth

So it is multiplication of monomials

Complete the following table of products:

Obtain the volume of rectangular boxes with the following length, breadth and height respectively.

*5a, 3a*^{2}, 7a^{8}- (
*2p, 4q, 8r*) *xy, 2x*^{2}y, 2xy^{2}- (
*a, 2b, 3c*

(i)

(ii)

(iii)

(iv) a x 2b x 3c = 6abc

Obtain the product of

- xy, yz, zx
- a, – a
^{2}a^{3} - 2, 4y, 8y
^{2}16y^{3} - a, 2b, 3c, 6abc
- m, – mn, mnp

(i)

(ii) –a

(iii) 1024y

(iv) 36a

(v) –m
