2.3x = 10.312 + 8.274
2.3x = 2 . 5 .312 + 23 .312
2.3x = 2 .312 (5+22)
2.3x = 2.312 . 9
2.3x = 2.314
3x = 2.314 : 2
3x = 314
=> x = 14.
\(2.3^x=10.3^{12}+8.27^4\)
\(\Rightarrow2.3^x=10.3^{12}+8.\left(3^3\right)^4\)
\(\Rightarrow2.3^x=10.3^{12}+8.3^{12}\)
\(\Rightarrow2.3^x=18.3^{12}\)
\(\Rightarrow2.3^x=2.3^{14}\)
\(\Rightarrow3^x=3^{14}\)
\(\Rightarrow x=14\)
Vậy x = 14
Ta có: 2.3x = 10.312 + 8.274
=> 2.3x = 10.312 + 23.(33)4
=> 2.3x = 10.312 + 23 . 312
=> 3x = 10.312 + 23.312 : 2
=> 3x = 5314410 + 2125764
=> 3x = 7440174
