[tex] \sqrt{ \frac{25}{144} } {}^{1} = \\ \sqrt{ \frac{25}{144}} {}^{ - 1} \\ \frac{ \sqrt{25} }{ \sqrt{144} } \\ \frac{ \sqrt{5 {}^{2} } }{ \sqrt{144} } \\ \frac{ \sqrt{25} }{144} \\ \frac{ \sqrt{5 {}^{2} } }{12 {}^{2}} \\ \frac{5}{ \sqrt{12 {}^{2} } } \\ \frac{ \sqrt{5 {}^{2} } }{ \sqrt{12 {}^{2} } } \\ \frac{5}{12} \\ \frac{ \sqrt{25}}{144} {}^{ - 1} \\ ( \frac{5}{12}) {}^{ - 1} \\ \frac{12}{5} \\ resposta \\ \frac{12}{5} \\ [/tex]
