Question

Tìm x :

\(32^x.16^x=1024\)

Tickkkkkk

Answer 1

32^x . 16^x = 1024

=> (2⁵)^x . (2⁴)^x = 2¹⁰

=> 2^5x . 2^4x      = 2¹⁰

=> 2^{5x + 4x}        = 2¹⁰

=> 2^9x              = 2¹⁰

=>  9x              = 10

=>    x              = 10 : 9

=>    x              = 10/9

Answer 2

TL:

\(32^x.16^x=1024\) 

\(\left(2^5\right)^x.\left(2^4\right)^x=1024\) 

\(2^{9x}=2^{10}\) 

\(\Rightarrow9x=10\Leftrightarrow x=\frac{10}{9}\) 

Vậy............

Answer 3

\(32^x.16^x=1024\)

\(\left(2^5\right)^x.\left(2^4\right)^x=1024\)

\(2^{9x}=2^{10}\)

\(=>9x=10\)

\(=>x=\frac{10}{9}\)

Answer 4

X=10/9
