    i cannot understand

    if we have a input signal such as X

    we dont need to use inverter in the first input of the gates

    can you explain why ?

    X prime is just an inverted state of X, also called X not.

    You dont need an inverter because the signal is inverted INSIDE the chip, rather than using an external chip.

    Inside the IC, there is an inverter. It takes the input X and flips it to X not (also called X` or X prime) Prime just indicates its the opposite.

    Example: If X=1, then X`=0. If X=0, then X`=1.
