Multiplikation af tre tal i videnskabelig notation

Multiplikation af meget store eller meget små tal er meget nemmere, når du bruger videnskabelig notation. Når vi ganger tal sammen skrevet i videnskabelig notation, så flyttes rundt på faktorerne. Derfor kan vi gange decimaltallene først og bruge potensregneregler til at gange 10'er potenserne sammen. Lavet af Sal Khan og Montereys Institut for teknologi og undervisning.
