Question 1111210
.


How @josgarithmetic and @mananth approach to this  " problem ",  it is out of good sense.



        Did I say  " out of good sense " ? - - -   No,  it is  AGAINST  of good sense.



First thing to do is to get a correct writing.


Only after that one can start solving problem.


So, dear visitor, write it in mathematically clear form and re-post.


Ignore that contributions from @josgarithmetic and @mananth as non-sensical.
