Answer 1

Step-by-step explanation:

${( - 4)}^{ - 7} \times {( \frac{1}{4} )}^{ - 7} \times {( \frac{3}{4} )}^{ - 3} \div {( { \frac{3}{4} )}^{2}) }^{ - 3} \\ = {( \frac{1}{4} )}^{7} \times {4}^{7} \times {( \frac{4}{3}) }^{3} \div {( \frac{4}{3}) }^{ 6} \\ 1 \times {( \frac{4}{3} )}^{3} \times {( \frac{3}{4} )}^{6} \\ 1 \times {( \frac{3}{4} )}^{3 - 6} \\ 1 \times \frac{( \frac{3}{4} )}{ - 3}$
