Answer 1

Resposta:

$a)5 {}^{7} . {5}^{2} = {5}^{7 + 2 } = {5}^{9}$

$b) {x}^{9} . {x}^{ - 6} = {x}^{9 + ( - 6)} = {x}^{9 - 6} = {x}^{3}$

$c) {3}^{9} \div {3}^{4} = {3}^{9 - 4} = {3}^{5}$

$d) {x}^{7} \div {x}^{ - 2} = {x}^{7 - ( - 2)} = {x}^{7 + 2} = {x}^{9}$

$e)( {2}^{5} ) {}^{3} = {2}^{5 \times 3} = {2}^{15}$

$f) ({x}^{3} ) {}^{ - 4} = {x}^{3 \times ( - 4)} = {x}^{ - 12}</p><p></p><p></p><p>[tex]f)( {x}^{3} ) {}^{ - 4} = {x}^{3 \times ( - 4)} = {x}^{ - 12}$

$g) (\frac{ {x}^{5} }{ {x}^{ - 3} }) {}^{4} = ( {x}^{5 - ( - 3)} ) {}^{4} = ({x}^{8} ) {}^{4} = {x}^{32}$
