Resolva As expressões corretamente simplificando

Answer 1

$~~~~~~~~~~\huge\sf \frac{ {9}^{4} \times {( {9}^{3} )}^{4} \times {( {9}^{2} )}^{5} }{ {9}^{7} } \\ \\ ~~~~~~~~~~ \huge\sf \frac{ {9}^{4} \times {9}^{12} \times {9}^{10} }{ {9}^{7} } \\ \\ ~~~~~~~~~~ \huge\sf \frac{ {9}^{4 + 12 + 10} }{ {9}^{7} } \\ \\ ~~~~~~~~~~ \huge\sf \frac{ {9}^{26} }{ {9}^{7} } \\ \\ ~~~~~~~~~~\huge\sf {9}^{26 - 7} \\ ~~~~~~~~~~ \sf\large\boxed{{\sf \huge {9}^{19} }}$
