Final answer:
The number of possible bracketings of 2³⁴⁵⁶ is 720.
Step-by-step explanation:
The number of possible bracketings can be determined using the concept of factorial. In this case, we have the number 2³⁴⁵⁶. Since the number has 6 digits, we need to find the number of ways we can group these digits. This can be done by finding the factorial of 6, which is 6! (6 factorial).
6! = 6 × 5 × 4 × 3 × 2 × 1 = 720
Therefore, there are 720 possible bracketings of 2³⁴⁵⁶.
