Cevap:
[tex]4^{3} (6^{-3} +12^{-3} )=4^{3} (6^{-3} +6^{-3} .2^{-3} )=4^{3} (6^{-3} (1+2^{-3}))=4^{3} (6^{-3} (1+\frac{1}{8} ))=4^{3} (6^{-3} (\frac{9}{8} ))=4^{3} (6^{-3} (\frac{3^{2} }{2^{3} } ))=4^{3} (\frac{1}{6^{3} } .\frac{3^{2} }{2^{3} } )=4^{3}.\frac{3^{2}}{3^{3}.2^{3}.2^{3} } =\frac{2^{3}.2^{3}.3^{2}}{3^{3}.2^{3}.2^{3} } =\frac{3^{2} }{3^{3} } =\frac{1}{3}[/tex]
