Answer 1

To write 0.0078125 in scientific notation, you first need to express it as a number between 1 and 10 multiplied by a power of 10.

1. Move the decimal point three places to the right to get 7.8125.
2. This adjustment means you must multiply by \(10^{-3}\) (since you moved the decimal three places to the right).

So, \(0.0078125\) in scientific notation is:

\[ 7.8125 \times 10^{-3} \]
