We commented and corrected on the remarks made by the referee in this
article as follows:
1) "is the Reimann-Liouville fractional derivative" sentences replaced by "is the Riemann-Liouville fractional derivative"
2) We write definition 2 again with existence condition.
We agree with the reviewer that the previous version of the article contained many misprints and inaccuracies. We carefully revised the article and in the new version eliminated all misprints and typos as much as possible.
