Answer :

To solve the problem of finding the ones digit of the cube of the number 3331, we'll break it down into clear, logical steps:

1. Identify the ones digit of the given number (3331):
- The ones digit is the digit in the unit's place of the number.
- For 3331, the ones digit is [tex]\(1\)[/tex].

2. Cube the identified ones digit:
- The cube of a number is that number raised to the power of 3.
- So, for the ones digit 1:
[tex]\[ 1^3 = 1 \][/tex]

3. Find the ones digit of the resulting cube:
- The ones digit of a number is the digit in the unit's place.
- In this case, the cube of 1 is 1. Thus, the ones digit of the resulting cube is [tex]\(1\)[/tex].

To summarize:
- The ones digit of 3331 is [tex]\(1\)[/tex].
- The cube of 1 is [tex]\(1\)[/tex].
- Hence, the ones digit of the cube of 3331 is [tex]\(1\)[/tex].

So, the ones digit of the cube of 3331 is [tex]\(1\)[/tex].
