Question

how do you write 0.099 in scientific notation? □ × 10□

Explanation:

Step1: Move decimal to get 1-10

To convert 0.099 to scientific notation, first move the decimal point 2 places to the right to get a number between 1 and 10: $0.099
ightarrow 9.9$

Step2: Determine exponent of 10

Since we moved the decimal point 2 places to the right (for a number less than 1), the exponent of 10 is negative 2: $10^{-2}$

Answer:

$9.9 \times 10^{-2}$
The first blank is $9.9$, the second blank is $-2$
