1000002

Answer 2

Answer:

the smallest 7 digit number with four digits will be 1000002.

Step-by-step explanation:

Let’s take three different digits with them being smallest too i.e. 0, 1, 2.

The numerical digit 0 cannot be placed in the first place while forming the number because then the number will have only 6 digits. The idea here is to take from smallest to biggest.

Smallest number other than 0 is 1, so we shall take 1.

Thereby, we shall place 0, (can be repeated five times) and then 2 will complete 7 digits.

Thus the smallest 7 digit number with four digits will be 1000002.
