Giải thích các bước giải:
Ta có:
\[\begin{array}{l}
{\left( {\frac{7}{{11}} - 0,63} \right)^{2012}} = {\left( {\frac{7}{{11}} - \frac{{63}}{{100}}} \right)^{2012}} = {\left( {\frac{{7.100 - 11.63}}{{{{11.10}^2}}}} \right)^{2012}}\\
= {\left( {\frac{{7.100 - 11.7.9}}{{{{11.10}^2}}}} \right)^{2012}} = {\left( {\frac{{7.100 - 7.99}}{{{{11.10}^2}}}} \right)^{2012}} = {\left( {\frac{7}{{{{11.10}^2}}}} \right)^{2012}}\\
= {\left( {\frac{7}{{11}}} \right)^{2012}}.\frac{1}{{{{10}^{2.2012}}}} = {\left( {\frac{7}{{11}}} \right)^{2012}}.\frac{1}{{{{10}^{4024}}}}
\end{array}\]
