Hi! I'm on a scientific notation unit and wanted to know if anyone could answer how exactly it is that you convert something into sn and also how to convert something out of it.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
