If it is possible to form a number which is a perfect square of a two ...
Problem Analysis:
We are given the number 739142658 and we need to form a perfect square using the second, fourth, and seventh digits of this number. We can use each digit only once. We need to determine if it is possible to form a perfect square of a two-digit odd number and if so, find the second digit of that two-digit odd number.
Solution:
Let's break down the problem into smaller steps:
Step 1:
We need to form a perfect square using the second, fourth, and seventh digits of the number 739142658. Let's extract those digits first.
The second digit is 3.
The fourth digit is 1.
The seventh digit is 2.
Step 2:
Now, let's try to form a perfect square using these digits. A perfect square is a number that can be expressed as the product of an integer with itself.
The possible two-digit odd numbers we can form using these digits are:
31
13
21
12
23
32
Step 3:
Now, let's check if any of these numbers is a perfect square.
31 is not a perfect square.
13 is not a perfect square.
21 is not a perfect square.
12 is not a perfect square.
23 is not a perfect square.
32 is not a perfect square.
Step 4:
Since none of the possible numbers we formed is a perfect square, it is not possible to form a perfect square of a two-digit odd number using the given digits.
Therefore, the correct answer is option 'D' (none).
Summary:
In this problem, we were given a number and asked to form a perfect square using specific digits from that number. We determined that it was not possible to form a perfect square of a two-digit odd number using those digits.
