[tex]\frac{7\times \:7^{16}\times \:7^9}{\left(7^4\right)^5} =\frac{7^{26}}{\left(7^4\right)^5} =\frac{7^{26}}{7^{20}} =7^6[/tex]
[tex]7\times \:7^{16}\times \:7^9 =7^{1+16+9} =7^{26}[/tex]
[tex]\left(7^4\right)^5 =7^{4\times \:5} =7^{20}[/tex]
[tex]=7^{26-20}=7^6[/tex]
Deci răspunsul va fi [tex]=7^6[/tex] .
Succes!
Sper că te-am ajutat!
