Question

express -73400000 in scientific notation

Answer 1

To express \(-73400000\) in scientific notation, you write it as:

\[
-7.34 \times 10^7
\]

Here's how it works:

1. Move the decimal point 7 places to the right to get \(7.34\).
2. Count how many places you moved the decimal point; in this case, it was 7 places.
3. Since the original number is negative, we keep the negative sign in the front.

Thus, \(-73400000\) in scientific notation is \(-7.34 \times 10^7\).
