1.	Find the number from each of the following expanded forms :(a) 8 × 104 + 6 × 103 + 0 × 102 + 4 × 101 + 5 × 100(b) 4 × 105 + 5 × 103 + 3 × 102 + 2 × 100(c) 3 × 104 + 7 × 102 + 5 × 100(d) 9 × 105 + 2 × 102 + 3 × 101
Answer» (a) 8 × 10⁴ + 6 × 10³ + 0 × 10² + 4 × 10¹ + 5 × 10⁰ = 8 × 10000 + 6 × 1000 + 0 × 100 + 4 × 10 + 5 × 1 = 80,000 + 6000 + 0 + 40 + 5 = 86,045 (b) 4 × 10⁵ + 5 × 10³ + 3 × 10² + 2 × 10⁰ = 400000 + 5000 + 300 + 2 = 4,05,302 (c) 3 × 10⁴ + 7 × 10² + 5 × 10⁰ = 40000 + 500 + 5 = 130,7051 (d) 9 × 10⁵ + 2 × 10² + 3 × 10¹ = 900000 + 200 + 30 = 9,00,230

Find the number from each of the following expanded forms :(a) 8 × 104 + 6 × 103 + 0 × 102 + 4 × 101 + 5 × 100(b) 4 × 105 + 5 × 103 + 3 × 102 + 2 × 100(c) 3 × 104 + 7 × 102 + 5 × 100(d) 9 × 105 + 2 × 102 + 3 × 101

Answer»

(a) 8 × 10⁴ + 6 × 10³ + 0 × 10² + 4 × 10¹ + 5 × 10⁰

= 8 × 10000 + 6 × 1000 + 0 × 100 + 4 × 10 + 5 × 1

= 80,000 + 6000 + 0 + 40 + 5

= 86,045

(b) 4 × 10⁵ + 5 × 10³ + 3 × 10² + 2 × 10⁰

= 400000 + 5000 + 300 + 2

= 4,05,302

= 40000 + 500 + 5

= 130,7051

(d) 9 × 10⁵ + 2 × 10² + 3 × 10¹

= 900000 + 200 + 30

= 9,00,230
