The number that least fits this set: (324, 441, 97 and 64) is _______________
Number Set Properties
We need to find the number that is different from the others in the set (324, 441, 97, 64). This involves identifying a pattern shared by most numbers in the set and finding the one that doesn't follow it.
Perfect Square Check
Let's check if each number is a perfect square, meaning it is the result of squaring an integer:
- 324: This number is a perfect square because $18 \times 18 = 18^2 = 324$.
- 441: This number is also a perfect square, as $21 \times 21 = 21^2 = 441$.
- 97: This number is not a perfect square. There is no integer whose square equals 97.
- 64: This number is a perfect square, since $8 \times 8 = 8^2 = 64$.
Outlier Number Found
Three numbers in the given set – 324, 441, and 64 – are perfect squares.
The number 97 is the only number in the set that is not a perfect square.
Therefore, 97 least fits this set because it does not share the common property of being a perfect square.
