Question

Write each of the following numbers in usual form: 

(i) 3.74 × 10⁵ 

(ii) 6.912 × 10⁸ 

(iii) 4.1253 × 10⁷ 

(iv) 2.5 × 10⁴ 

(v) 5.17 × 10⁸ 

(vi) 1.679 × 10⁹

Answer 1

= 374 x 10^(5-2) = 374 x 10³ = 374000

= 6912 x 10^(8-3) = 6912 x 10⁵ = 691200000

 = 41253 x 10)^(7-4) = 41253 x 10³ = 41253000

 = 25 x 10^(4-1) = 25 x 10³ = 25000

517 x 10^(6-2) = 517 x 10⁴ = 5170000

 = 1679 x 10^(9-3) = 1679 x 10⁶ = 1679000000
