Answer:
Explanation:
The dual of a function means replace AND with OR and replace OR with AND.
XOR gate of A , B is
So, Dual of A XOR B is ( replace AND with OR and OR with AND)
Complement of A XOR B is 
(In finding compliment AND becomes OR and OR becomes AND ).
By inter changing the above product of terms
Complement of 
So, Dual of A XOR B = Complement of A XOR B.

The cell reference refers to a cell on a worksheet and can be used in a formula to point another location.
Explanation:
A cell reference is a range of cells on a worksheet that can be used in a formula to find the values or data you want to calculate using that formula.
There are two types of cell references relative and absolute. they both behave differently when copied to other cells. Relative references change when a formula is copied to another cell.
Absolute reference remains constant even if they are copied. In a formula multiplications are performed before subtraction.
It does not change when the formula is copied or moved to another cell.
