x hoch a = b; a und b sind bekannt.

Hallo Anonymous,

x hoch a = b       ;    $${{\mathtt{x}}}^{{\mathtt{a}}} = {\mathtt{b}}$$   =>      x =  $${\sqrt[{{\mathtt{{\mathtt{a}}}}}]{{\mathtt{b}}}}$$  

Zahlenbeispiel:    x³ = 125      ;     x = $${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{125}}}} = {\mathtt{5}}$$
