Respuesta :

Given the following expression:

[tex]2^{3x-1}=32[/tex]

notice that 2^5 = 32,then:

[tex]2^{3x-1}=2^5[/tex]

this can give us the idea that both exponents on both sides of the equation are equal,then:

[tex]3x-1=5[/tex]

solving for x we get:

[tex]\begin{gathered} 3x-1=5 \\ \Rightarrow3x=5+1=6 \\ \Rightarrow x=\frac{6}{3}=2 \\ x=2 \end{gathered}[/tex]
