logic diagram ,,help


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 + X’Y’ + X’Z’.
b . B(A’C’+AC) + D’(A+B’C)


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.
