Løsningsvejledning

Hvis du vil gange potenser for den samme base, skal du tilføje deres eksponenter. Tilføj -11 og -31 for at få -42.

$$\frac{9\times 10^{8}\times \left(16\times 10^{-19}\right)^{2}}{667\times 10^{-42}\times 91\times 166\times 10^{-27}}$$

Hvis du vil gange potenser for den samme base, skal du tilføje deres eksponenter. Tilføj -42 og -27 for at få -69.

$$\frac{9\times 10^{8}\times \left(16\times 10^{-19}\right)^{2}}{667\times 10^{-69}\times 91\times 166}$$

Hvis du vil dividere potenserne for samme base, skal du subtrahere nævnerens eksponent fra tællerens eksponent.

$$\frac{9\times 10^{77}\times \left(16\times 10^{-19}\right)^{2}}{91\times 166\times 667}$$

Beregn 10 til potensen af 77, og få 100000000000000000000000000000000000000000000000000000000000000000000000000000.
