N3 - Multiplicative reasoning

N3.1

In N3.1 we learn how to multiply by powers of 10.
First of all, powers of ten are shown as external image gif.latex?10%5E%7Bx%7D

here are the powers of ten (these are infinite)

external image gif.latex?10%5E%7B10%20%7D = 10000000000

external image gif.latex?10%5E%7B9%20%7D = 1000000000

external image gif.latex?10%5E%7B8%20%7D = 100000000
