Question

how do you write 0.0023 in scientific notation? blank × 10blank submit

Explanation:

Step1: Recall scientific notation rules

Scientific notation is \( a \times 10^n \), where \( 1 \leq |a| < 10 \) and \( n \) is an integer. For \( 0.0023 \), we move the decimal point to get \( a \) between 1 and 10.

Step2: Determine \( a \) and \( n \)

Move the decimal in \( 0.0023 \) three places to the right to get \( a = 2.3 \). Since we moved the decimal to the right, \( n \) is negative, \( n=-3 \). So \( 0.0023 = 2.3 \times 10^{-3} \).

Answer:

The first box (for \( a \)) is \( 2.3 \), the second box (for the exponent) is \( -3 \). So the filled form is \( \boldsymbol{2.3} \times 10^{\boldsymbol{-3}} \)
