In order to write 428000 in scientific notation you would write 4.28 x 10 to which power?
Count how many places the decimal point must move to get back where it was. If the move is to the left make this count negative. This count is the power of 10. For 4.28 to get the decimal point back to where it was in 428000 (which is hiding after the last zero) it needs to move 5 places to the right. Therefore the power of 10 is 5. ie 428000 = 4.28 × 10⁵ in scientific notation.
