\(2.3^x=10.3^{12}+8.27^4\)
\(2.3^x=10.3^{12}+8.\left(3^3\right)^4\)
\(2.3^x=10.3^{12}+8.3^{12}\)
\(2.3^x=3^{12}.18\)
\(2.3^x=3^{12}.3^2.2\)
\(2.3^x=2.3^{14}\)
\(\Rightarrow x=14\)

\(2.3^x=10.3^{12}+8.27^4\)
\(\Rightarrow 2.3^x=2.3^{12}.5+2.3^{12}.2^2\)
\(\Rightarrow 2.3^x=2.3^{12}.(5+2^2)\Rightarrow 2.3^x=2.3^{12}.9\)
\(\Rightarrow 2.3^x=2.3^{12}.3^2\Rightarrow 2.3^x=2.3^{14}\Rightarrow 3^x=3^{14}\Rightarrow x=14\)
k mk nha bạn!
