How do you write 0.0000080 in scientific notation?

Question

× 10

Answer 1

To write the number 0.0000080 in scientific notation, you need 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 0.0000080 to the right until only one non-zero digit remains to its left. In this case, moving it 6 places to the right gives you \( 8.0 \).
2. Count how many places you moved the decimal point. Here, it's moved 6 places to the right, which means that \( n = -6\) (since we moved right).
3. Therefore, you can express 0.0000080 as:

\[ 8.0 \times 10^{-6} \]

So, the answer is \( 8.0 \times 10^{-6} \).
