Question

Como resolver essa simplificação.

Answer 1

$(ab)^{-1} .\frac{1}{c^{-2} } /\frac{b^{3} }{a^{3}c^{6}  }  \\\\\frac{1}{ab} .c^{2} /\frac{b^{3} }{a^{3}c^{6}  } \\\\\frac{c^{2} }{ab} /\frac{b^{3} }{a^{3}c^{6 }  }  = \frac{\frac{c^{2} }{ab} }{\frac{b^{3} }{a^{3 }c^{6}  } } = \frac{c^{2}.a^{3}c^{6}   }{ab^{4} } =\frac{a^{3} c^{8} }{ab^{4} } =\frac{a^{2}c^{8}  }{b^{4} }$
