Question

Simplify the given statement with proper explanation.​

Answer 1

Step-by-step explanation:

Simplify the following Boolean expression using Boolean algebra laws.

A+´AB=1.

´AB(A+ˊB)(ˊB+B)=ˊA.

( A+C)(AD+AˊD)+AC+C=A+C.

A+AB=A.

ˊA(A+B)+(B+AA)(A+ˊB)=A+B.

BC+BˊC+BA=B.

A+ˊAB+ˊAˊBC+ˊAˊBˊCD+ˊAˊBˊCˊDE=A+B+C+D+E.

A(A+B)=A.

Answer 2

$= 4 \frac{3}{8} \times \frac{27}{35} \times \frac{7}{9}$

$= \frac{35}{8} \times \frac{27}{35} \times \frac{7}{9}$

$= \frac{3 \times 7}{5 \times 8}$

$= \frac{21}{40}$
