# Write the smallest 4-digit number formed using the digits 8, 3, 0, 1: (1) 1038 (2) 1308 (3) 1083 (4) 0138

The smallest and largest 4-digit number are 1000 and 9999 respectively.

## Answer: The smallest 4-digit number formed using the digits 8, 3, 0, 1 is 1038.

Let's find the smallest 4-digit number using the given digits.

**Explanation:**

The given digits are 8, 3, 0, 1

Let's arrange them in ascending order:

0 < 1 < 3 < 8

As we need a 4 digit number, we cannot have it starting with 0.

Thus, the next smallest digit is 1.

Hence, the number will start with 1, and 0 will be positioned after 1 followed by 3 and 8, i.e, 1038.

### Thus, the smallest 4-digit number formed using the digits 8, 3, 0, 1 is 1038.
