*x*in the following equations. Homework Help ✎log

_{3}81 =*x*5

=^{x}3

*x*= 79

^{2}^{x}^{ }= 27^{x}^{−2}log

_{2}[log_{9}(log_{3}*x*)] = −1(

*x*− 3)(ln*x*− 2) = 0

3* ^{x}* = 81

5* ^{x}* = 5

^{−1}

log3* ^{x}* = log7

(3^{2})^{2}* ^{x}* = (3

^{3})

^{x}^{−2}

2^{−1} = log_{9}(log_{3}x)

3^{3} = *x*

*x* − 3 = 0

Solve for *x*.
