Question
Of the following numbers in scientific notation, what is the coefficient of the smallest number: 1.2×107
, 6.2×103
, 3.8×1010
?(1 point)

Answer 1

To determine the coefficient of the smallest number from the given options in scientific notation, we first need to compare their values.

1. \( 1.2 \times 10^7 = 12,000,000 \)
2. \( 6.2 \times 10^3 = 6,200 \)
3. \( 3.8 \times 10^{10} = 38,000,000,000 \)

Now, we can see:

- \( 1.2 \times 10^7 = 12,000,000 \)
- \( 6.2 \times 10^3 = 6,200 \)
- \( 3.8 \times 10^{10} = 38,000,000,000 \)

The smallest number is \( 6.2 \times 10^3 \).

Thus, the coefficient of the smallest number \( 6.2 \times 10^3 \) is \( \boxed{6.2} \).
