Question

find number of magnitude second in a day​

Answer 1

So, the number of seconds in a day is 86400 seconds. We need to know a simple rule of thumb, If a number is in the form a×10n where 5>a>0 , then the order of magnitude is n. If 10>a>5 , then the order of magnitude is (n+1).

hope this answer is helpful for you.
