Question

Find the difference on 7 and 8 digits smallest number

Answer 1

Hi ,

smallest 2 digit number = 10

smallest 3 digit number = 100

smallest 4 digit number = 1000

Similarly,

smallest 7 digit number = 1000000

smallest 8 digit number = 10000000

difference = 10000000 - 1000000

= 9000000

i hope this will useful to you.

Answer 2

Hi friend,
Smallest numbers of n digits start with 1 and will have n-1 number of zeroes.
Example:Smallest 2 digit number is 10 it starts with 1 and has one 0 i.e, n-1 zeroes .
So smallest 7 digit number is 1000000 and smallest 8 digit number is 10000000.
So difference between these two numbers =9000000.
