please explain step by step

3- Which one will show the decimal number in AL after performing the operations belows MOVAl. -2; SAL AL, 3 4. AL contains 003, after executing OR AL, mask, AL will be updated to 063. The MOV AL, Ox 03; OR AL, Ox mask The mask value is Ox 5- Find the bitmask to clear the bits in positions 0 through 3 of the register Al while passing through the bits in positions 4 through 7 . For example, Al contains binary bits of 11100111 B. After executing AND AL, mask B, AL will be updated to 11100000, what is the mask value in binary format B? MOV AL, 11100111 B. AND AL, mask B 6.AL contains 002, after executing OR AL, mask, AL will be updated to 042. The MOV Al, 0x 02: OR AL, Ox mask The mask value is 0x
