move the decimal point to form a number between 1 and 10. The power of 10 represents the number of places the decimal point is moved. In this case, to write 290,000,000 in scientific notation, we need to move the decimal point 8 places to the left to form the number 2.9. The power of 10 is then 8, since we moved the decimal point 8 places. Therefore, 290,000,000 in scientific notation is 2.9 x 10^8.
