Question 1120684
----------------------------------------------------
rationalize the denomination and simplify if possible:
15 over the square root of 11 + 6 
15 divided by square root 11 plus 6
---------------------------------------------------


Your written descriptions are not too clear.  Is your first example, {{{15/sqrt(11)+6}}}?  Or maybe {{{15/(sqrt(11)+6)}}} ?


-

{{{15/(sqrt(11)+6)}}}


{{{(15/(sqrt(11)+6))((sqrt(11)-6)/(sqrt(11)-6)))}}}


{{{(15*sqrt(11)-15*6)/(11-36)}}}
