How to calculate total no. of Logical expression in Boolean algebra if no. of variable is n ?

Suppose there are two variable A,B ? then what will be the total no of Logical expression ?

we couldn't calculate the logical expression according to the variables....we can calculate for logic gates and combinational circuits.
 

The number of logical expression is given by the formula 2^n.. It gives the maximum no. of logical expressions that can be obtained from the given variables...
 

yes prabakardeva is right we are not use logic 2^n for any normal Boolean variable and jayanth mentioned so many logic and recursive formula be used for more than one variable.

yeah..i understand thats what i m saying....
 

Hi the question is not clear it may be the maximum number of elements in a logical expression, It is 2^n
as SOP any logic can be expressed as MUX logic like for A & B
A'B' + A'B + AB' + AB
