Bits Combination on truth table with 9 inputs

hi Jessiebannon 

This can be find by using simple formula

General Formula to find the combinations of ‘n’ bit(s) = 2n

Because here is 9 table so we take here n = 9

Now put the value in above formula

So 29 = 512

For an n-input, the truth table will have 2^n (this is the general formula) values or combinations of bits. Therefore in this case, since the number of inputs is 9, so the value of the combination of the bits will be 2 raised to the 9th power or 2^9=2*2*2*2*2*2*2*2*2=512 combinations of bits.
