Calculation of the Number of Ways Elephant Can Pass Through the Jungle

To calculate the number of ways the elephant can pass through the jungle, we need to consider the given conditions:

1. The elephant does not like to backtrack. 2. The elephant passes through each fork only once. 3. Each fork has three road options to continue. 4. The elephant encounters a total of seven forks during the walk.

To calculate the number of ways, we can use the principle of multiplication. We multiply the number of options at each fork to get the total number of ways.

Let's break down the calculation step by step:

1. At the first fork, the elephant has three road options. 2. At the second fork, the elephant has three road options. 3. At the third fork, the elephant has three road options. 4. At the fourth fork, the elephant has three road options. 5. At the fifth fork, the elephant has three road options. 6. At the sixth fork, the elephant has three road options. 7. At the seventh and final fork, the elephant has three road options.

To calculate the total number of ways, we multiply the number of options at each fork:

3 * 3 * 3 * 3 * 3 * 3 * 3 = 2187

Therefore, the elephant can pass through the jungle in 2187 different ways.
