In 1-3 assume that B is a Boolean algebra with operations = and ‘ . Give the reasons needed to fill in the blanks in the proofs using only the axioms for a Boolean algebra.

1. Idempotent law for’ : For every a in B, ???
Proof: Let a be any element of B. Then
a = a .1                                                           ( a ) = a . ( a + a ¯ )                                         ( b ) = ( a ⋅ a ) + ( a ⋅ a ¯ )                       ( c )   = ( a ⋅ a ) + 0                                             (d)   = a . a                                                                     ( e )

To determine

a=a⋅1                     (a)_=a⋅(a+a¯)            (b)_=(a⋅a)+(a⋅a¯)     (c)_=(a⋅a)+0             (d)_=a⋅a                      (e)_

Explanation

Given information:

Let a be any element of B.

Concept used:

a¯+a=a+a¯     by the commutative law=1            by the complement law for 1

And

a¯⋅a=a⋅a¯     by the commutative law=0            by the complement law for 0

Calculation:

Let B be the Boolean algebra, with the operations, addition “ + ”and multiplication” ⋅ ”

Suppose a is any element of B.

Then, a¯ is the complement of a.

By tile Identity law for multiplication” ⋅ ”
