How do you write 9,304,000,000 in scientific notation

Answers

To do this, we move the decimal 9 places to the left.

We are left with 9.304 as our answer.

Now we have to write it in scientific notation.

9.304*10^9

We put 10 to the power of 9 because it is how much places we moved the decimal.

When writing scientific notation, our first number must be above 1 and below 10. That is why I did not make the answer 93 for example. 

Final answer: 9.304*10^9
9,304,000,000=9.304⋅10^9
