how the all gates can be made by only these two . Yes i know the circuit diagram of basic gates by universal gates which i have learnt. but if there is complex circuit like XOR gate or any other expression how would you make it please upload some links or material to explain the stuffs

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Instead of asking, finding out yourself is a very helpful learning experience.
Given two possible inputs x and y, how many possible logical functions are there?
a. Which functions of x and y can you implement using a single NAND gate? (Hint: The possible inputs are x and x, y and y, x and y).
b. Which functions of x and y can you implement using a NAND gate and inputs x, y, or a function found in (a)?
c. Which functions of x and y can you implement using a NAND gate and inputs x, y, or a function found in (a) or (b)?
and so on until you found how to implement each possible function.
