To write the number 0.09 x 10^12 in scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10.
First, let's count the number of times we move the decimal point to the right. Since we are multiplying by 10 raised to the power of 12, we need to move the decimal point 12 places to the right.
Starting with 0.09, we move the decimal point one place to the right, so we have 0.9. Moving it one more place to the right, we get 9.0 (or simply 9).
Finally, we move the decimal point 10 more places to the right, giving us the number 900,000,000,000.
Now, we can express this number in scientific notation by writing 9.0 (or 9) multiplied by 10 raised to the power of 11 (since we moved the decimal point 11 places to the right, from the original 0.09 to the final 9.0).
Therefore, 0.09 x 10^12 in scientific notation is 9.0 x 10^11.
