Question

How do I convert 350,000,000 into scientific notation?

Answer 1

Its 3.5 x 10^8

Answer 2

start at the end of the last zero. count the number of places to the left and stopping between 3 and 5. take the number of places and use that as the exponent of 10, i.e., \[10^x \] where x is the number of places.
