To find the number of different ways Gabriella can arrange her 4 posters in a row, we can use the concept of permutations. The number of ways to arrange \( n \) items is given by \( n! \) (n factorial), which is the product of all positive integers up to \( n \).
For Gabriella's 4 posters, we can calculate the number of arrangements as follows:
\[
4! = 4 \times 3 \times 2 \times 1 = 24
\]
Thus, the number of different ways Gabriella can arrange her 4 posters in a row is \( \boxed{24} \).
