Wurzelgleichungen
Aus Wikipedia:
Root equations are in the elementary algebra conditional equations, in which the unknowns (usually referred to as x) are at least once under a root. This may involve square roots or roots with any root exponent.
Many root equations can be resolved by isolating a root on one side of the equation and then potentiating the two sides of the equation with the root exponent (in the case of the square root of 2) . If necessary, repeat this procedure until all the roots are eliminated.
