To convert the number 0.0000069 into scientific notation, we want to express it in the form \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
1. Move the decimal point in 0.0000069 to the right until it is after the first non-zero digit, which is 6.9.
- This gives us 6.9.
2. Count how many places you moved the decimal point. In this case, you moved it 6 places to the right.
3. Since we moved the decimal to the right, \( n \) will be negative. Therefore:
- \( n = -6 \).
So, we can write:
\[
0.0000069 = 6.9 \times 10^{-6}
\]
Based on the options provided, the value in scientific notation is:
**6.9 × 10^-6**.
