$3^{3}\timesx-1=243$

$=>27\timesx=243+1$

$=>27\timesx=244$

$=>x=244:27$

$=>x=\dfrac{244}{27}$

Mấy cái \timex là nhân x nhé.

\(3^{3\times x-1}\) = 243

3\(^{3\times x-1}\) = 3⁵

3 \(\times\) \(x\) - 1 = 5

3 \(\times\) \(x\)      = 5 + 1

3 \(\times\) \(x\)      = 6

       \(x\)     =  6 : 3

       \(x\)     = 2

bài này cô giáo cho mình làm rồi . cũng dễ thôi mà.
