Answer 1

$\huge \mathbb\fcolorbox{pink}{pink}{Answer}$

Step-by-step explanation:

$( (\frac{1}{3} )^{x} )^{2} = \frac{1}{6561} \\ = (\binom{1}{3} ^{x} ) ^{2} = (\frac{1}{81} ) ^{2} \\ (\frac{1}{3} )^{x} = \frac{1}{81} \\ (\frac{1}{3} )^{x} = (\frac{1}{3} )^{4} \\ x = 4$

Answer 2

Step-by-step explanation:

$(( \frac{1}{3} ) {}^{x} ) {}^{2} = \frac{1}{6561} \\ \\ (( \frac{1}{3} ) {}^{x} ) {}^{2} = ( \frac{1}{81} ) {}^{2} \\ \\ ( \frac{1}{3} ) {}^{x} = \frac{1}{3 {}^{4} } \\ \\ x = 4$
