Hexadecimal numbers can be used in scientific notation.

Answer: Option B

This question is about how hexadecimal numbers work in MySQL.

Let's break it down:
* Hexadecimal numbers: These use base 16, using digits 0-9 and letters A-F to represent values. For example, A is 10, B is 11, and so on.
* Scientific notation: This is a way to represent very large or very small numbers using powers of 10 (e.g., 1.23 x 10^6).

Now, think about if you can combine these two ideas. Can you use scientific notation with hexadecimal numbers? The answer is No! Scientific notation is specifically for decimal numbers (base 10).

Therefore, the correct answer is Option B: False.
