Question

pls helpe solve this question by finding x answer should be -1​

Answer 1

Answer:

x=-1

Step-by-step explanation:

${ (\frac{ - 3}{4} )}^{4} \div { (\frac{ - 3}{4}) }^{3} = {(\frac{- 4}{3}) }^{x} \\ \frac{ { - 3}^{4} \times {4}^{3} }{ {4}^{4} \times { - 3}^{3} } = {(\frac{- 4}{3}) }^{x} \\ by \: using \: identity \: \\ {a}^{m} \div {a}^{n} = {a}^{m - n} \\ \frac{ {(4)}^{ - 1} }{ {(3)}^{ - 1} } = {(\frac{- 4}{3}) }^{x} \\ (\frac{ - 4}{3} ) ^{ - 1}= {(\frac{- 4}{3}) }^{x} \\ x = - 1$
