Explicación paso a paso:

$E=[(\frac{1}{5} )^{-2} +2(\frac{3}{2} )^{-2} +(\frac{1}{3} )^{2} +(\frac{1}{7} )^{-2} +(\frac{1}{6} )^{-1} ]^{\frac{1}{2} } \\\\E=[(\frac{5}{1} )^{2} +2(\frac{2}{3} )^{2} +(\frac{1}{3} )^{2} +(\frac{7}{1} )^{2} +(\frac{6}{1} )^{1} ]^{\frac{1}{2} } \\\\E=[25+\frac{8}{9} +\frac{1}{9} +49+6 ]^{\frac{1}{2} } \\\\E=[81]^{\frac{1}{2} }=[9^{2} ]^{\frac{1}{2} }=9^{2.\frac{1}{2} } =9$
