which is the odd one out? 16 36 64 27 81
27. The others are prefect squares.
The odd one out is the number that is NOT a square.
To determine the odd one out among the numbers 16, 36, 64, 27, and 81, we need to identify the pattern or rule that applies to the numbers.
Looking at the numbers, we can see that 16, 36, and 64 are all perfect squares (4^2, 6^2, 8^2, respectively). Additionally, 81 is also a perfect square (9^2). However, 27 is not a perfect square.
Based on this pattern, 27 is the odd one out because it's the only number that is not a perfect square.
To find the answer, you can identify the pattern or rule among the numbers and analyze their properties. In this case, recognizing the concept of perfect squares helped solve the problem.
