The set of numbers arranged in descending order is:
7.6 × 10^-25, 7.2 × 10^-25, 7.2 × 10^-30, 7 × 10^-30
To determine which set of numbers is arranged in descending order, we need to compare the numbers in each set.
The first set is:
7.6 × 10^(-25), 7.2 × 10^(-30), 7.2 × 10^(-25), 7 × 10^(-30)
The second set is:
7 × 10^(-30), 7.2 × 10^(-25), 7.2 × 10^(-30), 7.6 × 10^(-25)
The third set is:
7.6 × 10^(-25), 7.2 × 10^(-25), 7.2 × 10^(-30), 7 × 10^(-30)
The fourth set is:
7.2 × 10^(-30), 7 × 10^(-30), 7.6 × 10^(-25), 7.2 × 10^(-25)
To determine which set is arranged in descending order, we need to compare the numbers from left to right. The numbers with larger values will come before the numbers with smaller values.
Comparing the first set, we see that 7.6 × 10^(-25) is larger than 7.2 × 10^(-30), so it should come before it. However, the third number, 7.2 × 10^(-25), is smaller than 7.6 × 10^(-25), so it should come after it. This means that the first set is not arranged in descending order.
Comparing the second set, we find that 7.2 × 10^(-25) is larger than 7 × 10^(-30), so it should come before it. However, the fourth number, 7.6 × 10^(-25), is larger than 7.2 × 10^(-25), so it should come before it. This means that the second set is also not arranged in descending order.
Comparing the third set, we see that 7.6 × 10^(-25) is larger than 7.2 × 10^(-30), so it should come before it. The third number, 7.2 × 10^(-30), is smaller than both 7.6 × 10^(-25) and 7.2 × 10^(-25), so it should come last. This means that the third set is not arranged in descending order.
Comparing the fourth set, we find that 7.2 × 10^(-25) is larger than 7 × 10^(-30), so it should come before it. The first number, 7.2 × 10^(-30), is smaller than both 7.2 × 10^(-25) and 7 × 10^(-30), so it should come last. This means that the fourth set is arranged in descending order.
Therefore, the set of numbers arranged in descending order is:
7.2 × 10^(-30), 7 × 10^(-30), 7.6 × 10^(-25), 7.2 × 10^(-25)
