To calculate the total number of different 6-symbol PIN codes that can be created using both letters and digits, we need to determine the total number of available characters and then raise that number to the power of the length of the PIN code (which is 6 in this case).
1. **Determine the total number of characters available**:
- There are 26 letters in the English alphabet (A-Z).
- There are 10 digits (0-9).
Combining both, we have:
\[
\text{Total characters} = 26 \, (\text{letters}) + 10 \, (\text{digits}) = 36
\]
2. **Calculate the total number of different PIN codes**:
Since each of the 6 positions in the PIN code can be filled by any of the 36 characters, the total number of different 6-symbol PIN codes can be calculated as:
\[
\text{Total PIN codes} = 36^6
\]
3. **Compute \(36^6\)**:
Calculating \(36^6\):
\[
36^6 = 2,176,782,336
\]
Therefore, the total number of different 6-symbol PIN codes that can be created using letters and digits is **2,176,782,336**.
