Question

2^2x-3=2⁹ cầu cứu !

Answer 1

\(2^{2x-3}=2^9\)

`=> 2x-3=9`

`2x=9+3`

`2x=12`

`x=12:2`

`x=6`

Vậy `x=6`

Answer 2

\(2^{2x-3}=2^9\Leftrightarrow2x-3=9\Leftrightarrow2x=12\Leftrightarrow x=6\)

Answer 3

2^2x-3=2⁹

=> 2x - 3 = 9

     2x = 9 + 3

     2x = 12

       x = 12 : 2 

       x = 6

vậy x = 6

Answer 4

X bằng 6
