Explanation:

Step1: Identify the number of textbooks

Keshawn has 4 textbooks (Spanish, biology, history, writing).

Step2: Use the permutation formula for n distinct objects

The number of permutations of \( n \) distinct objects is \( n! \) (n factorial). For \( n = 4 \), we calculate \( 4! \).

Step3: Calculate 4 factorial

\( 4! = 4\times3\times2\times1 = 24 \).

Answer:

24
