@Akshansh Bhura: Welcome to math.SE: since you are new, I wanted to let you know a few things about the site. In order to get the best possible answers, it is helpful if you say in what context you encountered the problem, and what your thoughts on it are; this will prevent people from telling you things you already know, and help them give their answers at the right level. When its a homework question, please use the 'homework' tag. People will still help, don't worry! Consider editing you question

What have you tried? You should start with change of variable $t=\log x$, then $dt=\frac{dx}{x}$
