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 = 10.3¹² + 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 !!!!!!!!!!!!!!!!!!!!!!!

\(2\cdot3^x=10\cdot3^{12}+8\cdot27^4\) 

\(2\cdot3^x=2\cdot5\cdot3^{12}+2^3\cdot\left(3^3\right)^4\) 

\(2\cdot3^x=2\cdot5\cdot3^{12}+2^3\cdot3^{12}\) 

\(2\cdot3^x=2\cdot3^{12}\left(5+2^2\right)\) 

\(3^x=3^{12}\left(5+4\right)\) 

\(3^x=3^{12}\cdot9\) 

\(3^x=3^{12}\cdot3^2\) 

\(3^x=3^{14}\) 

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

=> 3^x = 9.3¹²

=> 3^x = 3².3¹²

=> 3^x = 3¹⁴

=> x = 14

vậy_

2.3^x = 10.3¹²  + 8.27⁴

2.3^x = 2 . 5 .3¹² + 2³ .3¹²

2.3^x = 2 .3¹² (5+2²)

2.3^x = 2.3¹² . 9

2.3^x = 2.3¹⁴

3^x = 2.3¹⁴ : 2

3^x = 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: 2.3^x = 10.3¹² + 8.27⁴

=> 2.3^x = 10.3¹² + 2³.(3³)⁴

=> 2.3^x = 10.3¹² + 2³ . 3¹²

=> 3^x = 10.3¹² + 2³.3¹² : 2

=> 3^x =  5314410 + 2125764

=> 3^x = 7440174

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=18.531441

2.3^x=9565938

3^x=9565838:2

3^x=4782969
