# Find the product of the following pairs of monomials:i. 3, 7xii. – 7x, 3yiii. – 3a, 5abiv. 5a2, – 4av. vi. Xy2, x2yvii. x3y5, xy2viii. abc, abcix. xyz. x2yzx. a2b2c3, abc2

i. 3, 7x

= 3×7x

= 21x

ii. – 7x, 3y

= -7 ×3×x ×y

= -21xy

iii. – 3a, 5ab

= -3 ×5 ×a ×a ×b

= -15 b

= -15 = -15 b

iv. 5a2, – 4a

= (5 = -20 )

= -20 v. = )

= ( )

= ( )

= vi. Xy2, x2y

= y2 + 1

= vii. x3y5, xy2

= = viii. abc, abc

= a× b× c × a × b × c

= (a × a) × (b × b) x ( c × c)

= × × = ix. xyz. X2yz

= ( x × x2 ) x (y × y) × (z× z)

= x3 x. a2b2c3, abc2

= (a2 × a) x ( b2 × b)x ( c3 × c)

= × × Rate this question :
