1. The student should have used a calculator or manual calculation to find the exact value of the square root of 2, which is approximately 1.414, not 1.5.
2. The student incorrectly assumed that the square root of 2 is a rational number, when it is actually irrational.
3. The student failed to recognize that the square root of 2 cannot be expressed as a simple fraction or terminating decimal.
4. The student should have used the correct mathematical notation and terminology when discussing irrational numbers.
5. The student should have provided a more accurate approximation of the square root of 2, such as 1.414, rather than rounding to 1.5.
6. The student should have explained why the square root of 2 is irrational, perhaps by referencing the proof that it cannot be expressed as a ratio of two integers.
7. The student should have considered the context of the problem and determined whether an approximate or exact value was required.
8. The student should have checked their work for accuracy and consistency with known mathematical facts.
9. The student should have used appropriate units and labels in their calculations, if applicable.
10. The student should have sought clarification or additional resources if they were unsure about the properties of irrational numbers.
