ayuda otra ves doy corona al q responda bien :v​

Answer 1

Explicación paso a paso:

=   $\frac{\left(\frac{4}{5}\right)^{21}}{\frac{\left(\frac{8}{10}\right)^8}{\left(\frac{4}{5}\right)^5}}$

= $\frac{\left(\frac{4}{5}\right)^{21}\left(\frac{4}{5}\right)^5}{\left(\frac{8}{10}\right)^8}$

$=\frac{\left(\frac{4}{5}\right)^{21}\left(\frac{4}{5}\right)^5}{\left(\frac{8}{10}\right)^8}$

$=\frac{\left(\frac{4}{5}\right)^{26}}{\left(\frac{8}{10}\right)^8}$

$=\frac{\left(\frac{4}{5}\right)^{26}}{\frac{4^8}{5^8}}$

$=\frac{\left(\frac{4}{5}\right)^{26}}{\frac{4^8}{5^8}}$

$=\frac{\left(\frac{4}{5}\right)^{26}}{\frac{4^8}{5^8}}$

$=\frac{4^{18}\cdot \:5^8}{5^{26}}$

$=\frac{4^{18}}{5^{26-8}}$

$=\frac{4^{18}}{5^{18}}$ esta es la respuesta

espero que te ayude
