Answer:

(\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3=\frac{81}{25}

Step-by-step explanation:

Given expression is,

(\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3

By solving the given expression,

(\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3=(\frac{\frac{1}{3}+\frac{1}{2}}{\frac{1}{5}})^{-1}+3

                     =(\frac{\frac{2+3}{6}}{\frac{1}{5}})^{-1}+3

                     =(\frac{\frac{5}{6}}{\frac{1}{5}})^{-1}+3

                     =(\frac{5}{6}\times \frac{5}{1})^{-1}+3

                     =(\frac{25}{6})^{-1}+3

                     =\frac{6}{25}+3

                     =\frac{6+(25\times 3)}{25}

                     =\frac{81}{25}
