You have 26 options for the uppercase letter. There are 8 symbols total in the string. So the letter can be in (8 choose 1)=8 positions. Therefore, there are $26 \cdot 8$ options for the letter.
For the remaining symbols in the string, you have 7 characters. Each character has 10 possibilities: 0, 1, 2, ..., 9. Therefore, there are $10^7$ possibilities for the numerical symbols.
Combining the two together, you have $26\cdot8 \cdot 10^7$ possibilities for the string.
Note: people in the community will often ask you to show an attempt before helping you with a problem. Just something to keep in mind for the future. :)
