(2x-1)\(^3\)=125
2x-1=5
2x=5-1
2x=4
x=4:2
x=2
(2x - 1)= 125
\(\Rightarrow\) (2x - 1)3 = 53
\(\Rightarrow\) 2x - 1 = 5
2x = 5 + 1
2x = 6
x = 6 : 2
x = 3.
\(\left(2x.1\right)^3=125\)
\(\left(2x.1\right)^3=5^3\)
\(\Rightarrow2x.1=5\)
\(\Rightarrow\) \(2x=5\)
\(\Rightarrow x=\dfrac{5}{2}\)
(2x . 1)3 = 125
\(\Rightarrow\) (2x)3 = 53
\(\Rightarrow\) 2x = 5
\(\Rightarrow\) x = 2,5
