Place the numbers in descending order.

2.3 × 10−^10; 3.2 × 10−^10; 2.3 × 10−^12; 2.3 × 10−8

1 answer

To arrange the numbers in descending order, we can consider the scientific notation and the values they represent:

  1. \( 2.3 \times 10^{-8} \) is equal to \( 0.000000023 \)
  2. \( 2.3 \times 10^{-10} \) is equal to \( 0.00000000023 \)
  3. \( 3.2 \times 10^{-10} \) is equal to \( 0.00000000032 \)
  4. \( 2.3 \times 10^{-12} \) is equal to \( 0.0000000000023 \)

Now we can arrange them in descending order based on their values:

  1. \( 2.3 \times 10^{-8} \)
  2. \( 3.2 \times 10^{-10} \)
  3. \( 2.3 \times 10^{-10} \)
  4. \( 2.3 \times 10^{-12} \)

So the ordered list in descending order is:

\( 2.3 \times 10^{-8}, 3.2 \times 10^{-10}, 2.3 \times 10^{-10}, 2.3 \times 10^{-12} \)
