vereinfachen [(9x^{1/2}y^{-3})(2x^{-1}y)^2]^{1/2}

Lösung

vereinfachen

[(9 x^{\frac{1}{2}} y^{- 3}) (2 x^{- 1} y)^{2}]^{\frac{1}{2}}

\frac{6}{x ^{\frac{3}{4}} y ^{\frac{1}{2}}}

Schritte zur Lösung

((9 x^{\frac{1}{2}} y^{- 3}) (2 x^{- 1} y)^{2})^{\frac{1}{2}}

Wende Exponentenregel an:

(a \cdot b)^{n} = a^{n} b^{n}

((9 x^{\frac{1}{2}} y^{- 3}) (2 x^{- 1} y)^{2})^{\frac{1}{2}} = (9 x^{\frac{1}{2}} y^{- 3})^{\frac{1}{2}} ((2 x^{- 1} y)^{2})^{\frac{1}{2}}

= (9 x^{\frac{1}{2}} y^{- 3})^{\frac{1}{2}} ((2 x^{- 1} y)^{2})^{\frac{1}{2}}

Vereinfache

((2 x^{- 1} y)^{2})^{\frac{1}{2}} : \frac{2 y}{x}

= (9 x^{\frac{1}{2}} y^{- 3})^{\frac{1}{2}} \frac{2 y}{x}

(9 x^{\frac{1}{2}} y^{- 3})^{\frac{1}{2}} = \frac{3 x ^{\frac{1}{4}}}{y ^{\frac{3}{2}}}

= \frac{2 y}{x} \cdot \frac{3 x ^{\frac{1}{4}}}{y ^{\frac{3}{2}}}
