3rd and 4th question

The least number of gates that could be used to build logic circuit with the boolean expression (A+B+C)' would be. Note: do not worry about what is available in the hardware labs. 2 O 3 An NOR gate with inverters connected to each input behaves like vhcih gate AND OR XOR NAND a The simplest form of X=((A+B) + AC)' X= AB X=(A+B)' +C X = A'+ (AC) X= ABC When you write the output equation for a function in POS, you look for places where the truth table output is: either Oor 1 None of the above The minimum expression for X that can be read from the Karnaugh map shown is
