             AND operation = 10100000

Step-by-step explanation:

OR operation:  A + B = adding the two binary numbers together, starting from the least significant bit (LSB) and moving to the Most significant bit (MSB)

AND operation: A*B, multiplying the two binary numbers together.

NOT: taking the opposite of each binary digit

XOR: if either of the two binary numbers is 1, then the result is 1, but if they are both 1 or both 0, then the result becomes 0.
