The number 0.023 written in scientific notation is:
\( 2.3 \times 10^{-2} \)
Here's the breakdown:
1. Move the decimal point in 0.023 two places to the right to get 2.3.
2. Count how many places you moved the decimal point (which is 2 places to the right). Since we moved it to the right, the exponent will be negative.
3. Thus, it becomes \( 2.3 \times 10^{-2} \).
So the correct answer is \( 2.3 \times 10^{-2} \).
\( 2.3 \times 10^{-2} \)
