(c) 725 x10⁻⁵ kg                     (d) 0.02 x10⁻⁸
Ans {(a) 1.168x10⁻²⁴ (b) 3.2x10⁶ (c)7.25 g (d) 2x10⁻¹⁰}
Solution:
⇒  1.168 x 10³ x 10⁻²⁷  
⇒  1.168 x 10³⁻²⁷ 
⇒  1.168 x 10⁻²⁴ 
(b) 32 x 10⁵ 
⇒  3.2 x 10 x 10⁵  
⇒  3.2 x 10¹⁺⁵  
⇒  3.2 x10⁶     ----------------Ans
(c) 725 x 10⁻⁵ Kg  
⇒  7.25 x10² x10⁻⁵ x 10³ g 
⇒  7.25 x 10²⁻⁵⁺³ g 
⇒  7.25 x10⁰ g             [∴ 10⁰ = 1]
