Write (T) for true and (F) for false for each of the statements given below:
The number of digits in a perfect square is even.

Answer

To determine whether the statement "The number of digits in a perfect square is even" is true or false, we can analyze the number of digits in various perfect squares.

### Step-by-Step Solution:

1. **Understand what a perfect square is**: A perfect square is a number that can be expressed as the square of an integer. For example, \(1^2 = 1\), \(2^2 = 4\), \(3^2 = 9\), \(4^2 = 16\), \(5^2 = 25\), and so on.

2. **Calculate the squares of some integers**:
- \(1^2 = 1\) (1 digit)
- \(2^2 = 4\) (1 digit)
- \(3^2 = 9\) (1 digit)
- \(4^2 = 16\) (2 digits)
- \(5^2 = 25\) (2 digits)
- \(6^2 = 36\) (2 digits)
- \(7^2 = 49\) (2 digits)
- \(8^2 = 64\) (2 digits)
- \(9^2 = 81\) (2 digits)
- \(10^2 = 100\) (3 digits)
- \(11^2 = 121\) (3 digits)

3. **Count the number of digits**:
- From the calculations, we observe:
- Perfect squares of \(1\), \(2\), and \(3\) have 1 digit (odd).
- Perfect squares of \(4\), \(5\), \(6\), \(7\), \(8\), and \(9\) have 2 digits (even).
- Perfect squares of \(10\) and \(11\) have 3 digits (odd).

4. **Conclusion**: The number of digits in a perfect square can be either odd or even. Therefore, the statement "The number of digits in a perfect square is even" is **False**.

### Final Answer:
(F)
