7.6 × 10−25, 7.2 × 10−30, 7.2 × 10−25, 7 × 10−30
7.6 times 10 Superscript negative 25 Baseline , 7.2 times 10 Superscript negative 30 Baseline , 7.2 times 10 Superscript negative 25 Baseline , 7 times 10 Superscript negative 30 Baseline
7.2 × 10−30, 7 × 10−30, 7.6 × 10−25, 7.2 × 10−25
7.2 times 10 Superscript negative 30 Baseline , 7 times 10 Superscript negative 30 Baseline , 7.6 times 10 Superscript negative 25 Baseline , 7.2 times 10 Superscript negative 25 Baseline
7.6 × 10−25, 7.2 × 10−25, 7.2 × 10−30, 7 × 10−30
7.6 times 10 Superscript negative 25 Baseline , 7.2 times 10 Superscript negative 25 Baseline , 7.2 times 10 Superscript negative 30 Baseline , 7 times 10 Superscript negative 30 Baseline
7 × 10^−30, 7.2 × 10^−25, 7.2 × 10^−30, 7.6 × 10^−25
7.6 × 10−25, 7.2 × 10−25, 7.2 × 10−30, 7 × 10−30 (7.6 times 10 to the negative 25, 7.2 times 10 to the negative 25, 7.2 times 10 to the negative 30, 7 times 10 to the negative 30)
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 and their exponents.
In the first set of numbers:
7.6 × 10^-25
7.2 × 10^-30
7.2 × 10^-25
7 × 10^-30
Comparing the exponents, the numbers with smaller exponents are 10^-30. Comparing the coefficients (7.6, 7.2, 7.2, 7), the largest number is 7.6.
So, the first set of numbers arranged in descending order is:
7.6 × 10^-25, 7.2 × 10^-25, 7.2 × 10^-30, 7 × 10^-30
