hi ^^

Draw the logic diagram of the following expression. The diagram should correspond directly to the equation. Assume that the complements of the inputs are not available:
a . XYZ + XY + XZ.
b . B(AC+AC) + D(A+BC)


what does it mean ?
do i have to draw the inverter? or not?
should i use the sum of products form?

In item a you don't need to use inverters. Use De Morgan's law and implement X'Y' and X'Z' using nor gates instead of nand gates.
In item b you should use inverters.
