Compare the following numbers:

(i) 2.7 × 10¹²; 1.5 × 10⁸

(ii) 4 × 10¹⁴; 3 × 10¹⁷

(i) We have,

2.7 × 10¹² and 1.5 × 10⁸

So, in order to find the greater quantity among the two we will follow following steps:

Since,

2.7 is greater than 1.5 and 10¹² is also greater than 10⁸

Hence,

2.7 × 10¹² > 1.5 × 10⁸

(ii) We have,

4 × 10¹⁴ and 3 × 10¹⁷

So, in order to find the greater quantity among the two we will follow following steps:

Since,

4 is greater than 3 but 10¹⁷ is greater than 10¹⁴

Hence,

3 × 10¹⁷ > 4 × 10¹⁴
