Question

Which answer shows 0.00897 written in scientific notation?
0.897 times 10 Superscript negative 2
8.97 times 10 Superscript negative 3
8.97 times 10 Superscript negative 2
8.97 times 10 Superscript 3

Answer 1

To convert 0.00897 into scientific notation, we want to express it in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.

1. Move the decimal point in 0.00897 to the right until it is located after the first non-zero digit:
- 0.00897 becomes 8.97 when we move the decimal 3 places to the right.

2. Since we moved the decimal 3 places to the right, we will have:
\[
0.00897 = 8.97 \times 10^{-3}
\]

Thus, the answer in scientific notation is:
**8.97 times 10 Superscript negative 3**

So, the correct choice is **8.97 times 10 Superscript negative 3**.
