Write the following expression with as few symbols as possible, using the notational conventions:

My name is Ann [436]

Answer:

The simplified expressions are (x + y·z' + t) and x·(x + y' + z) respectively.

Step-by-step explanation:

The expressions provided are:

$(i)\ x+((y\times (z')) +t)\\\\(ii)\ x\times((x+(y'))+z)$

(i)

Simplify the first expression with as few symbols as possible:

$x+((y\times (z')) +t)=x+(yz'+t)$

$=x+yz'+t$

(ii)

Simplify the second expression with as few symbols as possible:

$x\times((x+(y'))+z)=x\times ((x+y')+z)$

$=x (x+y'+z)$

Thus, the simplified expressions are (x + y·z' + t) and x·(x + y' + z) respectively.
