Tính \[\frac.\frac{1}{{{4^2}}}.3 + \left( {\frac{8} - \frac.\frac{5}} \right):\frac\]

\[\frac.\frac{1}{{{4^2}}}.3 + \left( {\frac{8} - \frac.\frac{5}} \right):\frac\]

\( = \frac{{{{15.4}^2}}} + \left( {\frac{8} - \frac.\frac{5}} \right).\frac\)

\(\begin{array}{l} = \frac + \left( {\frac{8} - \frac{1}{4}} \right).\frac\\ = \frac{7} + \left( {\frac - \frac} \right).\frac\\ = \frac{7} + \frac.\frac\\ = \frac{7} + \frac.\frac\\ = \frac{7} + \frac{3}\\ = \frac{7} + \frac{6}\\ = \frac\end{array}\)
