Math Problem Statement

Would you classify the number 169 as a perfect square, a perfect cube, both, or neither? Explain.

Solution

The question asks whether the number 169 is a perfect square, a perfect cube, both, or neither.

Let's analyze this:

  1. Perfect Square: A number is a perfect square if it can be expressed as the square of an integer. The square root of 169 is: 169=13\sqrt{169} = 13 Since 13 is an integer, 169 is a perfect square.

  2. Perfect Cube: A number is a perfect cube if it can be expressed as the cube of an integer. The cube root of 169 is approximately: 16935.528\sqrt[3]{169} \approx 5.528 Since 5.528 is not an integer, 169 is not a perfect cube.

Conclusion:

169 is a perfect square but not a perfect cube.
