(iii) 82934000000
(V) 23000000
​

Answer 1

(ɪ) 538 = 5.38 × 10^2

(ɪɪ) 6428000 = 6.428000 × 10^6

(ɪɪɪ) 82934000000 = 8.2934000000 × 10^10

Answer 2

(i) 538 = 500 + 30 + 8

(ii) 64,28,000 = 60,00,000 + 4,00,000 + 20,000 + 8000

(iii) 82,93,40,00,000 = 80,00,00,00,000 + 2,00,00,00,000 + 90,00,00,000 + 3,00,00,000 + 40,00,000

(iv) 2,30,00,000 = 2,00,00,000 + 30,00,000
