Answer 1

Respuesta:

$\mathrm{Aplicar\:las\:leyes\:de\:los\:exponentes}:\quad \left(a^b\right)^c=a^{bc}$

$\left(\left\{\left(\frac{3}{5}\right)^6\right\}^0\right)^{123} + (\frac{2}{7} )^{2}$

$=\left(\left(\frac{3}{5}\right)^{6\cdot \:0}\right)^{123} + ( \frac{2^{2} }{7^{2} } )$

$=\left(\left(\frac{3}{5}\right)^{0}\right)^{123} +\frac{4}{49}$  

$=\left(\left(\frac{3}{5}\right)^{0 * 123 }\right)+\frac{4}{49}\\\\=\left(\left(\frac{3}{5}\right)^{0}\right)+\frac{4}{49}\\\\1+\frac{4}{49}\\\\\frac{53}{49}$
