Multiplikation og division med videnskabelig notation

I denne video skal vi se, hvordan man kan bruge videnskabelig notation, når udtryk skal forenkles. Potenser med samme grundtal, der ganges eller divideres med hinanden kan reduceres ved at addere eller subtrahere eksponenterne. For eksempel 7 ⋅ 10⁵ / (2 ⋅ 10⁻²)(2,5 ⋅10⁹) kan reduceres til 1,4 ⋅10⁻². Videnskabelig notation gør det nemmer at reducere komplicerede ligninger, hvor potenser med samme grundtal ganges og divideres med hinanden. Lavet af Sal Khan.
