Answer 2

The correct answer is:

7.6 × 10−25, 7.2 × 10−25, 7.2 × 10−30, 7 × 10−30

Answer 3

To arrange the numbers in descending order, we need to compare the values of the numbers. In this case, the numbers are expressed in scientific notation, where the exponent represents the power of 10.

To compare the numbers, we should start by comparing the coefficients (the numbers before the "× 10^" part). The larger the coefficient, the larger the number will be.

Let's compare the coefficients of the given numbers:

7 × 10^(-30)
7.2 × 10^(-25)
7.2 × 10^(-30)
7.6 × 10^(-25)

Comparing the coefficients, we see that 7.6 is the largest, followed by 7.2, and then 7. Finally, we need to compare the exponents. In this case, the exponents are negative numbers, and the larger negative exponent corresponds to a smaller number.

Comparing the exponents, we see that 10^(-25) is larger than 10^(-30), meaning it corresponds to a smaller number.

Using this information, we can order the numbers in descending order:

7.6 × 10^(-25), 7.2 × 10^(-25), 7 × 10^(-30), 7.2 × 10^(-30)

Therefore, the set of numbers arranged in descending order is:
7.6 × 10^(-25), 7.2 × 10^(-25), 7 × 10^(-30), 7.2 × 10^(-30)
