To write a number in scientific notation, we need to move the decimal point so that there is only one non-zero digit to the left of it.
Starting with 290,000,000, we move the decimal point 8 places to the left to get 2.9.
Since we moved the decimal point 8 places to the left, we need to multiply the number by 10 raised to the power of 8.
Therefore, the number 290,000,000 in scientific notation is 2.9 x 10^8.
