Question

alguém poderia me responder pfvr​

Answer 1

$a) {3}^{4} \times {3}^{3} \times {3}^{4} = {3}^{4 + 3 + 4} = {3}^{11} \\ b) {2}^{3} \times {3}^{ - 4} \times {2}^{ - 5} \times {2}^{8} = {2}^{3 - 4 - 5 - 8} = {2}^{2} = 4 \\ c) {( \frac{2}{3}) }^{5} \times {( \frac{2}{3} )}^{ - 3} = { (\frac{2}{3}) }^{2} = \frac{4}{9} \\ d) {3}^{3} \times {3}^{ - 2} \times {3}^{5} \times {3}^{4} \times ( { {3}^{2} })^{4} = {3}^{3} \times {3}^{ - 2} \times {3}^{5} \times {3}^{4} \times {3}^{8} = {3}^{3 - 2 + 5 + 4 + 8} = {3}^{18} \\ e)( { \frac{m}{4} })^{ - 3} \times ( { \frac{m}{4} })^{ 4} = \frac{m}{4} \\ f) \frac{ {7}^{2} \times {7}^{5} }{ {7}^{3} \times {7}^{4} } = \frac{ {7}^{7} }{ {7}^{7} } = {7}^{0} = 1$
