Question

Place the numbers in descending order.

2.3 × 10−10
; 3.2 × 10−10
; 2.3 × 10−12
; 2.3 × 10−8 theres only 4 boxes

Answer 1

To place the numbers in descending order, we can first compare the exponents and then the coefficients.

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

Now, let's compare them based on their powers of 10:

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

Now, putting them in descending order:

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 final order is:

**2.3 × 10−8, 3.2 × 10−10, 2.3 × 10−10, 2.3 × 10−12**.
