Answer 2

Answer:

1023456

Step-by-step explanation:

To form the smallest number using the string of digits, we need to arrange the digits in ascending order.

So that, the smallest digit comes first and the largest digit comes last.

Here, the ascending order of digits is 0 < 1 < 2 < 3< 4 < 5 < 6

So we form the number as 0123456.

But here, this number is equal to 123456 and which is a 6-digit number.

So we can not put 0 in the beginning of the number.

Hence exchange the position of 0 by 1 as it is next in the ascending order.

So , smallest 7 digit number now is 1023456.
