Answer 2

1.02×10⁹ is the corect answer. The Rule is simple, we always put a point after the leftmost number (1 in this case) and write approximately two to three numbers after the point, which are successing the left most number (0&2 in this case). Then we give a multiplication sign (×) after it and writing 10 ,we raise it to a number < which represents the total number of digits one has to walk from the ones place to reach that leftmost number( in this case we Walked  9 digits from the unit's place to reach our left most number i.e. 1). I hope its detailed well
