Explanation of how 2n came as the number of non-square numbers:

Definition of non-square numbers:
Non-square numbers are natural numbers that are not perfect squares. In this case, the numbers between 80 and 81 are considered.

Understanding the concept:
When we have two consecutive natural numbers n and n + 1, the number of non-square numbers between them is given by 2n.

Explanation:
- Let's take the lower number as n = 80.
- The next consecutive number is n + 1 = 81.
- Since we are looking at the numbers between 80 and 81, we are essentially looking at non-square numbers.
- To find the number of non-square numbers, we use the formula 2n.
- Substitute n = 80 into the formula: 2 × 80 = 160.
- Therefore, there are 160 non-square numbers between 80 and 81.

Conclusion:
The number of non-square numbers between 80 and 81 is 160, calculated using the formula 2n. This formula is derived from the concept of consecutive natural numbers and their relationship to non-square numbers.
