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

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

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

=>x = 14

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

\(2.3^x=10.3^{12}+8.\left(3^3\right)^4\)

\(2.3^x=10.3^{12}+8.3^{12}\)

\(2.3^x=3^{12}.18\)

\(2.3^x=3^{12}.3^2.2\)

\(2.3^x=2.3^{14}\)

\(\Rightarrow x=14\)

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

\(\Rightarrow 2.3^x=2.3^{12}.5+2.3^{12}.2^2\)

\(\Rightarrow 2.3^x=2.3^{12}.(5+2^2)\Rightarrow 2.3^x=2.3^{12}.9\)

\(\Rightarrow 2.3^x=2.3^{12}.3^2\Rightarrow 2.3^x=2.3^{14}\Rightarrow 3^x=3^{14}\Rightarrow x=14\)

k mk nha bạn!

Tớ không biết viết số mũ nên tớ viết ^ là mũ nhé.

2.3^x = 10.3^12 + 8. (3^3)^4

2.3^x = 10.3^12 + 8.3^12

2.3^x = 18.3^12

2.3^x = 2.9.3^12

3^x    = 9.3^12

3^x    = 3^2.3^12

3^x    = 3^14

=> x = 14

Hơi dài dòng, bạn thông cảm nhé.

tìm x thì cần jk lời giải hả bạn

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

\(2.3^x=10.3^{12}+8.3^{12}\)

\(2.3^x=3^{12}\left(10+8\right)\)

\(2.3^x=18.3^{12}\)

\(3^x=9.3^{12}\)

\(3^x=3^{14}\)

\(x=14\)

2.3^x=10.3^12+8^27^4

2.3^x=10.3^4.3+8.27^4

2.3^x=10.27^4+8.27^4

2.3^x=(10+8).27^4

2.3^x=18.27^4

2.3^x=2.9.3^12

2.3^x=2.3^2.3^12

2.3^x=2.3^14

x=14

Thanks mn nha

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

Hok Tốt !!!!!!!!!!!!!!!!!!!!!!!
