We have been asked to find the solution of

[tex] {Log_{(2x-3)}}^{125}=3\\
\\
\text{we can re-write after Removing logarithm as below}\\
\\
(2x-3)^3=125\\
\\
(2x-3)^3=5^3\\
\\
\text{Now take cubed root on both the sides we get}\\
\\
2x-3=5\\
\\
\text{Add 3 on both the sides we get}\\
\\
2x=8\\
\\
\text{Divide both the sides by 2 we get}\\
\\
x=4
[/tex]
