To solve this problem, we need to convert 8.54 kilobytes (KB) to bytes (B) using the given conversion rate, then express the result in scientific notation.

Solution:

1. Conversion Factor:
   $1 \, \text{KB} = 1024 \, \text{B}$

2. Calculate the Bytes: $8.54 \, \text{KB} \times 1024 \, \text{B/KB} = 8744.96 \, \text{B}$

3. Express in Scientific Notation: To express 8744.96 in scientific notation, we write it as: $8.74496 \times 10^3 \, \text{B}$ Rounding to three significant figures, we get: $8.74 \times 10^3 \, \text{B}$

Final Answer:

$8.74 \times 10^3 \, \text{B}$
