1)

1v1&0=1

1v0&0=1

2)

0&0&1=0

0&1&1=0

1&0&1=0

1&1&1=1

Answer 2

1) 1vX&0 This expression is a logical operation. The "v" symbol represents the logical OR operation, and the "&" symbol represents the logical AND operation. The "X" is a variable that can take on the values of either 0 or 1.

To evaluate this expression, we need to consider all possible combinations of the variable "X" and apply the logical operations.

When X=0: 1v0 = 1 (logical OR) 1vX&0 = 1 (logical OR)

When X=1: 1v1 = 1 (logical OR) 1vX&0 = 1 (logical OR)

So, the expression 1vX&0 evaluates to 1 for all values of X.

2) X&X&1 This expression also involves logical AND operations. When evaluating this expression, we consider all possible combinations of the variable "X" and apply the logical AND operations.

When X=0: 0&0 = 0 (logical AND) 0&0&1 = 0 (logical AND)

When X=1: 1&1 = 1 (logical AND) 1&1&1 = 1 (logical AND)

So, the expression X&X&1 evaluates to 0 when X=0 and 1 when X=1.
