How do I convert 3427 into scientific notation?

A number in is in the form
##a * 10^b##
Generally
##1 <= a < 10## For ##3427## the decimal point is on the right of 7 ##3427.0## We need to move the decimal such that ##1 <= a < 10## will be satisfied. However we also need to retain its value. For each movement of the decimal place to the left multiply the number by 10. To satisfy ##1 <= a < 10## the decimal place needs to move by 3 places to the left. Hence we have ##3.427 * 10^3## For the longer version of converting to scientific notation we have ##3427 * (1) = 3427## ##3427 * (1/10 * 10) = 3427## ##(3427 * 1/10) * 10 = 3427## ##342.7 * 10 = 3427## ##342.7 * 1 * 10 = 3427## ##342.7 * (1/10 * 10) * 10 = 3427## ##(342.7 * 1/10) * (10 * 10) = 3427## ##34.27 * (10^2) = 3427## ##34.27 * 1 * (10^2) = 3427## ##34.27 * (1/10 * 10) * (10^2) = 3427## ##(34.27 * 1/10) * (10 * 10^2) = 3427## ##3.427 * 10^3 = 3427##
