Question 288986
.
square root of 27 over p squared
~~~~~~~~~~~~~~~~~~~~~~~~



The answer in the post by @mananth,   {{{(3/p)*sqrt(3)}}},  strictly speaking, is incorrect.


The correct answer is   {{{(3/abs(p))*sqrt(3)}}},   using the absolute value  |p|.


The expression   {{{(3/p)*sqrt(3)}}}   works correctly only for positive values of  ' p '.


For negative values of  ' p '  it does not work correctly.


The expression   {{{(3/abs(p))*sqrt(3)}}}   works  UNIVERSALLY  for positive values and for negative  values of  ' p '.



        Therefore, this form,  {{{(3/abs(p))*sqrt(3)}}},   is preferable,  and even more, 

                is the  {{{highlight(highlight(UNIQUELY))}}}  {{{highlight(highlight(acceptable))}}}  correct form.
