Answer» Correct Answer - Option 1 : 24

Given :  x = 597 × 1022 + 73.5 × 1021 

Calculation

 x = 597 × 1022 + 73.5 × 1021

= 597 × 10 × 1021 + 73.5 × 1021

= 5970 × 1021 + 73.5 × 1021

= (5970 + 73.5) × 1021 = 6043.5 × 1021 = 6.0435 × 1024

On comparing it with the standard form of x which is x = 6.0435 × 10m  we get

m = 24
