Answer 1

Answer:

${ \frac{2}{3} }^{x - 1} = { \frac{2}{3} }^{2 - x } \\ \\ = > x - 1 = 2 - x \\ = > x + x = 2 + 1 \\ = > 2x = 3 \\ = > x = \frac{2}{3}$

$({3}^{ - 1} - {5}^{ - 1})^{ - 1} \div ( {2}^{ - 1} - {3}^{ - 1} ) ^{ - 1} \\ = > ( ({a}^{b}) ^{c} = {a}^{bc} by \: applying \: this \: law \: ) \\ = > ( {3}^{ - 1 \times - 1} - {5}^{ - 1 \times - 1} ) \div ( {2}^{ - 1 \times - 1} - {3}^{ - 1 \times - 1} ) \\ = > ( {3}^{1} - {5}^{1} ) \div ({2}^{1} - {3}^{1} ) \\ = > ( - 2) \div (- 1) \\ = > 2$

hope it helps
