Answer 1

Step-by-step explanation:

1)

${( \frac{1}{3} )}^{3} \times {( \frac{1}{3}) }^{4} \times {( \frac{1}{3}) }^{5} \\ = {( \frac{1}{3}) }^{3 + 4 + 5} \\ = {( \frac{1}{3} )}^{12} \ \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \frac{1}{ {3}^{12} }$

2)

${ - 3}^{5} \times { - 3}^{4} \times { - 3}^{6} \\ = {( - 3)}^{5 + 4 + 6} \\ = { ( - 3)}^{15}$

3)

${3}^{4} \times { (\frac{4}{3}) }^{3} \\ = {3}^{4} \times {4}^{3} \times {3}^{ - 3} \\ = {4}^{3} \times {3}^{4 - 3} \\ = 64 \times 3 \\ = 192$

4)

$\frac{ {5}^{ - 4} }{ {5}^{ - 3} } \times {5}^{2} \\ = {5}^{ - 4} \times {5}^{2} \times {5}^{3} \\ = {5}^{ - 4 + 2 + 3} \\ = {5}^{ - 4 + 5} \\ = {5}^{1} = 5$

5)

${( - 2)}^{3} \times {5}^{3} \\ = {( - 2 \times 5)}^{3} \\ = {( - 10)}^{3} \\ = - 1000$

hope you get your answers
