\(3636:\left(12.x-91\right)=36\)
\(\left(12.x-91\right)=3636:36\)
\(\left(12.x-91\right)=101\)
\(\left(12.x\right)=101+91\)
\(\left(12.x\right)=192\)
\(x=192:12\)
\(x=16\)
Vậy x = 16

\(2.3^x=162\)
\(3^x=162:2\)
\(3^x=81\)
\(3^4=81\)
Vậy x = 4

\(2^x.2^4=128\)
\(2^x.2^4=2^7\)
\(x+4=7\)
\(x=7-4\)
\(x=3\)
Vậy \(x=3\)
