$\square$
Solution
Solution Steps
Step 1: Place Candle A in the first spot.
This step is straightforward as Candle A is fixed in the first position.
Step 2: Place Candle B in the second spot.
Similarly, Candle B is fixed in the second position, leaving no choice for these two spots.
Step 3: Arrange the remaining \(n-2\) candles.
Since there are \(n-2\) candles left and \(n-2\) spots, the number of ways to arrange these is given by the factorial of \(n-2\), i.e., \((n-2)!\).
Calculation:
The calculation for the number of arrangements is \((n-2)!\) = \(6!\).
Final Answer
The total number of ways to arrange the candles is \((n-2)!\) = 720.
