1. The Boolean expression B⊕E is a simplified version of expression A BE + BCDE+ BC D E + A B D E + B C D E + A B D E then which of the following choice is correct? don't care conditions doesn't existdon't care conditions existd( 16, 18, 20, 23, 27, 29) is the set of don't care conditionsd( 16, 20, 22, 27, 29) is the set of don't care conditions

Reduced form of the given expression is B ⊕ E : A BE + BCDE + B C D E + A B D E + B C D E + A B D E Now we draw a K-map for 5 variables : Since we can realize B ⊕ E i.e. BE + B E as shown above, the K-map drawn should have don't care conditions that will be taken into consideration and will be grouped; along with l's. ∴ We have don't care conditions with a set d( 16, 20, 22, 27, 29).
