Answer 2

.
${3}^{4x } = 1 \div 81$
ANS. VALUE OF x IS = -1

STEP BY STEP EXPLANATION...
${3}^{4x } = 1 \div 81$
$therefore \: {3}^{4x} = {81}^{ - 1}$
$= {3}^{4x} = {3}^{ - 4}$
and as basis of both the terms are same so therefore the power will also be same ...so

$4x = - 4$
$therefore \: x = - 4 \div 4$
therefore....
$x = - 1$
