\(\left(\dfrac{1}{2}\right)^{3x-1}=\dfrac{1}{32}\\ \Rightarrow\left(\dfrac{1}{2}\right)^{3x-1}=\dfrac{1}{2^5}\\ \Rightarrow\left(\dfrac{1}{2}\right)^{3x-1}=\left(\dfrac{1}{2}\right)^5\\ \Rightarrow3x-1=5\\ \Rightarrow3x=6\\ \Rightarrow x=2\)
(\(\dfrac{1}{2}\))3x - 1 = \(\dfrac{1}{32}\)
3x - 1 = \(\dfrac{1}{32}\) : (\(\dfrac{1}{2}\))
3x - 1 = \(\dfrac{1}{16}\)
3x = \(\dfrac{1}{16}\) + 1
3x = \(\dfrac{17}{16}\)
x = \(\dfrac{17}{16}:3\)
x = \(\dfrac{17}{48}\)

mà 3x - 1 là số mũ hay biểu thức bình thường vậy bạn ????
