3 × 10^4) − (5 × 10^2).

3 × 10^4 − 5 × 10^2

3 x 10^4 = 30000

5 x 10^2 = 500

30000 - 500 = 29500

29500 written in scientific notion is 2.95 x 10^4

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.
