Beste AntwortHallo Anonymous,
ich glaube, du hast das so gemeint:
$${\sqrt{{\mathtt{300}}}} = {\sqrt{{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{100}}}}$$ = $${\mathtt{10}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{3}}}}$$
Noch ein Beispiel: (erst faktorisieren !)
$${\sqrt{{\mathtt{12\,500}}}} = {\sqrt{{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{10}}{\mathtt{\,\times\,}}{\mathtt{10}}}}$$ = $${\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{10}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5}}}}$$
2. Beispiel:
$${\sqrt{{\mathtt{5\,400}}}}$$ = $${\sqrt{{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{5}}}}$$ = $${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}}}$$ =
$${\mathtt{30}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{6}}}}$$
