\(132-2x+8=46\Leftrightarrow140-2x=46\Leftrightarrow2x=94\Leftrightarrow x=47\)

\(2,\)

\(a,132-2\left(x-4\right)=46\)

\(\Rightarrow-2\left(x-4\right)=-86\)

\(\Rightarrow x-4=43\)

\(\Rightarrow x=47\)

Vậy: \(x=47\)

\(b.9x-4x=6^{17}:6^{15}+48:12\)

\(\Rightarrow5x=6^2+4\)

\(\Rightarrow5x=40\)

\(\Rightarrow x=8\)

Vậy: \(x=8\)

\(c,2^{x+3}.4=64\)

\(\Rightarrow2^{x+3}=16\)

\(\Rightarrow2^{x+3}=2^4\)

\(\Rightarrow x+3=4\)

\(\Rightarrow x=1\)

Vậy: \(x=1\)
