Answer 1

Respuesta:

$\frac{ {5}^{3} }{ {5}^{2} } = {5}^{3 - 2} = 5$

$\frac{ {9}^{12} }{ {9}^{4} } = {9}^{12 - 4} = {9}^{8}$

$\frac{ {12}^{9} }{ {12}^{ - 2} } = {12}^{9 - ( - 2)} = {12}^{9 + 2} = {12}^{11}$

$( \frac{2y}{5x} )^{2} = \frac{4y ^{2} }{25x^{2} }$

$( \frac{8x}{6x} )^{8} = \frac{64x ^{8} }{48 {x}^{8} } = \frac{64}{48} =\frac{64 \div 16}{48 \div 16} = \frac{4}{3}$

$( \frac{4m}{2n} )^{3} = \frac{64m ^{3} }{ {8n}^{3} } =\frac{64 \div 8m ^{3} }{ {8 \div 8n}^{3} } \frac{8 m ^{3} }{ {n}^{3} }$

$( {5y})^{4} = {625y}^{4}$

$(7b) ^{a} = {7b}^{a}$

$(xy)^{9} = {xy}^{9}$

$(12a) ^{6} = 2,985,984 {a}^{6}$
