Arithmetic Rules

Mathematical Foundations (Discrete Structures)

Instructions Complete the following problems by filling in the blanks with amounts represented with the fewest char- acters possible (e.g., use 8 instead of 23, but use 27 in lieu of 128). Blanks here permit strings (i.e., an ordered set of one or more characters). How many length-6 ternary strings are palindromes? How many length-6 binary strings are palindromes? How many length-5 binary strings are palindromes
