\(2.3^x=10\cdot3^{12}+8.27^4\)

\(10.3^{12}+8.27^4=10.3^{12}+8.3^{12}\)

\(10.3^{12}+8.3^{12}=3^{12}\cdot\left(10+8\right)=3^{12}\cdot18=3^{12}\cdot2\cdot3^2=3^{14}\cdot2\)

=>x = 14

=>x=14

2.3^x = 10.3^12+8.27^4

x               = 14      

2.3^x = 10.3¹² + 8.27⁴

=> 2.3^x = 10.3¹² + 2³ . (3³)⁴

=> 2.3^x = 10.3¹² + 8.3¹²

=> 2.3^x = (10 + 8).3¹²

=> 2.3^x = 18.3¹²

=> 2.3^x = 2.3² . 3¹²

=> 2.3^x = 2.3¹⁴

=> x = 14

\(2.3^x=10.3^{12}+8.27^4\)

\(\Leftrightarrow2.3^x=2.5.3^{12}+2^3.\left(3^3\right)^4\)

\(\Leftrightarrow2.3^x=2.5.3^{12}+2^3.3^{12}\)

\(\Leftrightarrow2.3^x=2.3^{12}\left(5+2^2\right)\)

\(\Leftrightarrow2.3^x=2.3^{12}.9\)

\(\Leftrightarrow2.3^x=2.3^{12}.3^2\)

\(\Leftrightarrow2.3^x=2.3^{14}\)

\(\Leftrightarrow x=14\)

Vậy x=14

2.3^x = 10.3¹² + 8.27⁴

=> 2.3^x = 10.3¹² + 8.(3³)⁴

=> 2.3^x = 10.3¹² + 8.3¹²

=> 2.3^x = (10 + 8).3¹²

=> 2.3^x = 18.3¹²

=> 3^x = 18 : 2.3¹²
