Use the following definition of the binary operator \(\mathrm{XOR}\) , denoted by \(\oplus,\) for Exercises \(69-81 .\) $$ x \oplus y=\left\\{\begin{array}{ll}{1} & {\text { if exactly one of the bits } x \text { and } y \text { is } 1} \\ {0} & {\text { otherwise }}\end{array}\right. $$ Evaluate each. $$ 1 \uparrow(0 \oplus 1) $$
The set \(D_{70}=\\{1,2,5,7,10,14,35,70\\}\) of positive factors of 70 is a boolean algebra under the operations \(\oplus, \odot,\) and ' defined by \(x \oplus y=\operatorname{lcm}\\{x, y\\}\) \(x \odot y=\operatorname{gcd}\\{x, y\\},\) and \(x^{\prime}=70 / x .\) Compute each. $$(5 \oplus 7)^{\prime}$$
Prove algebraically. $$(x+y) z=x z+y z$$
Determine if each is a boolean expression, where each variable is boolean. $$\left(\left(x y^{\prime}\right)^{\prime}\right)^{\prime}$$
Using a Karnaugh map, simplify each sum of minterms. $$x y+x y^{\prime}$$
