The question asks, "How many bits are there in E3H?" E3H is a hexadecimal (base 16) number. Each hexadecimal digit represents 4 bits. - E = 4 bits - 3 = 4 bits So, E3 is 2 hexadecimal digits, which is **8 bits** in total. The correct answer is: - **8**

Let's go through the steps to determine how many bits are in E3H: 1. **Identify the number system:** E3H is a hexadecimal (base 16) number. The suffix "H" indicates hexadecimal. 2. **Recall how many bits each hex digit represents:** Each hexadecimal digit corresponds to 4 bits because: \[ 16 = 2^4 \] 3. **Count the number of hex digits:** E3H has 2 digits: **E** and **3**. 4. **Calculate total bits:** Since each digit is 4 bits, the total number of bits is: \[ 2 \text{ digits} \times 4 \text{ bits per digit} = 8 \text{ bits} \] **Final answer:** **E3H is represented using 8 bits.**
