Question 1136045


A five letter word is formed with the letters {{{a}}}, {{{e}}}, {{{u}}}, {{{r}}}, {{{s}}}, {{{t}}}. How many of them are palindromes? 

There are {{{6}}} options for the {{{1st}}} letter, {{{6}}} for the {{{2nd }}}letter, and {{{6}}} for the {{{middle}}} letter. 

There's {{{only}}} {{{1}}} way to fill up the last two letters (matching it to the first 2 so it becomes a palindrome). 

So, {{{6 * 6 * 6 = 216}}}
