The number of variables in a function is odd and the number of minterms with even number of 0's are same as the number of minterms with odd number at 1 's, the expression formed can be represented in __________ as well as __________ form.

With odd number of variables (n) terms with even number of 0's and terms with odd number of 1 's are the same. Thus the k-map for the above condition with minterms represented by terms with even number of 0's is for n = 3 ∴ The expression can be represented by equivalence (EX NOR) or (EX OR) expressions.
