Answer 2

Answer:

${ (\frac{5}{13} )}^{2 - 3x} \times { (\frac{5}{13}) }^{5x - 4} = { (\frac{5}{13} )}^{7x + 6}$

${a}^{m} \times {a}^{n} = {a}^{m + n}$

${ (\frac{5}{13})}^{2 - 3x + 5x - 4} = { (\frac{5}{13} )}^{7x + 6}$

${ (\frac{5}{13}) }^{2x - 2} = { (\frac{5}{13}) }^{7x + 6}$

$if \: bases \: are \: same \: power \: also \: be \: equal$

$so \: 2x - 2 = 7x + 6 \\ 5x = - 8 \\ x = \frac{ - 8}{5}$
