Question

If a=70,b=4 and c=10,verify a multiple (b multiple c) = (a multiple b) multiple c

Answer 1

Answer:

(a × b) × c = a × (b × c) Hence proved

Step-by-step explanation:

70 × (4 × 10)

= 70 × 40 = 2800                                                                                   [ a × (b × c)]

(70 × 4) × 10

= 280 × 10 = 2800

∵ 70 × (4 × 10) = (70 × 4) × 10 = 2800

∴ (a × b) × c = a × (b × c)

Hence proved
