States in DFA
If NFA has 'n' states then how DFA can have 2^n states. Please help me in understanding how this is true. As per my understanding every DFA is NFA then how no of states can be more in DFA than nfa Please suggest Thanks

Doubt DFA
1.The minimum no of state in DFA that accept L={an n is multiple of 3 but not 5} Ans 15 i did it and found that 3,5 relatively prime so 3*5=15 2.The minimum no of state in DFA that accept L={an n is multiple of 2 but not 4} Ans 4 and done and found that 2,4 not relatively prime so max(2,4) =4 Can't a Conclude it??? Edited. thanks for rectification.

TOC : Minimum State in Finite Automata ( virtualgate )
For a binary string x = a0a1 · · · an−1 define val(x) to be the value of x interpreted as a binary number, where a0 is the most significant bit. More formally, val(x) is given by How many minimum states will be in a finite automaton that accepts exactly the set of binary strings x such that val(x) is divisible by either 4 or 5. Ans is 5 or 20?

No of states in Minimal DFA
Ques: Let ∑= {0, 1} What will be the number of states in minimal DFA, if the Binary number string is congruent to (mod 8)? *[ Can anybody explain this as I am getting 8 states for this since remainders will be 8 (0,1,2,3,4,5,6,7). But the answer is 4].
