Question

You have to solve this in exponential equation. And I will mark it brainlist. ​

Answer 1

A.T.Q

$\\ = > \: \: \: \: \: 3^{4x} = \frac{1}{81} \\ \\ = > \: \: \: \: \: \: {3}^{4x} = \frac{1}{ {3}^{4} } \\ \\ = > { \3}^{4x} = { \3}^{ - 4}$

$= > \: \: \: \: \: \: \: \: \: \: \: \: 4x = - 4 \\ \\ = > \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{ - 4}{4} \\ \\ = > \huge \: x = - 1$

so, your required answer to this question is,

x = —1
