Write down the value of `(bar(X)+X) and (X.bar(X))` in Boolean algebra.

Write down the values of (barX+X) and (X.barX) in Boolean algebra.

If bar(X)_(1) and bar(X)_(2) are the means of two series such that bar(X)_(1)

If bar(a)=i+j+k, bar(b)=i-j+2k and bar(c)=x""i+(x-2)j-k . If the vector bar(c) lies in the plane of bar(a) and bar(b) then x equals to

What will be the value of input A and B for the boolean equation (bar(A+B))*(bar(A*B))=1 ?

In the Boolean algebra bar((bar(A).bar(B))). A equal to

The average of n numbers x_(1), x_(2), ……. X_(n) is bar(x) . Then the value of sum_(i=1)^(n) (x_(1) - bar(x)) is equal to

In the figure above, bar(AB)"||"bar(CD) . Find the value of x.
