Question

solve and find the value of x ​

Answer 1

Answer:

$\frac{5}{7}$

Step-by-step explanation:

${3}^{3x - 5} = \frac{1}{ {81}^{x} }$

${3}^{3x - 5} = \frac{1}{ { ({3}^{4}) }^{x} }$

${3}^{3x - 5} \times {3}^{4x} = 1$

${3}^{3x - 5 + 4x} = 1$

$so \: 7x - 5 = 0$

$so \: \: \: x \: = \frac{5}{7}$
