How do you write 340000000 scientific notation?

Answer 1

Put the decimal point after the first non-zero digit and copy all digits except trailing zeros. Multiply this by 10 to some power. To work out the power, count how many digits the decimal point must move to get back where it was in the original number; if the decimal point has to move to the left, make the count negative. Thus:

340000000 = 3.4 x 10^8

Answer 2

To write a given number in scientific notation, bring the decimal point until it becomes a number between 1 inclusive and 10 exclusive. Then multiply it with the corresponding power of 10. In this case, it is 3.4 x 10^8.
