Question

alguém me ajuda pfv e urgente eu preciso disso ​

Answer 1

a)

$( {3}^{8} \div {3}^{7} ) \times {3}^{4}$

${3}^{8 - 7} \times {3}^{4}$

$3 \times {3}^{4}$

${3}^{1 + 4} = {3}^{5}$

b)

$( {10}^{8} \div {10}^{4}) \div 10$

$( {10}^{8 - 4}) \div 10$

${10}^{4} \div 10$

${10}^{4 - 1} = {10}^{3}$

c)

$( {10}^{2} ) ^{3} \times 10$

${10}^{2 \times 3} \times 10$

${10}^{6} \times 10$

${10}^{6 + 1} = {10}^{7}$

d)

${3}^{8} \div (3 \times {3}^{5} )$

${3}^{8} \div ({3}^{1 + 5} )$

${3}^{8} \div {3}^{6}$

${3}^{8 - 6} = {3}^{2}$
