GATE CSE 2002 | Question: 7
Express the function $f(x,y,z) = xy' + yz'$ with only one complement operation and one or more AND/OR operations. Draw the logic circuit implementing the expression obtained, using a single NOT gate and one or more AND/OR gates ... (without expressing its switching function) into an equivalent logic circuit that employs only $6$ NAND gates each with $2$-inputs.

Are the below two problems decidable ?
1. A turing machine prints a specific letter . 2.If L is CFL then L' is also CFL . For the second one ,it is known that L' will not be CFL but then why can't we design any algorithm for it ,since it is true that complement of CFL will never be true so then what is the essence here with respect to talking about decidable and undecidable ?

what happens when we take union of two languages and then take its reversal ?
If I have two languages then according to me (L1 UNION L2 )^r =L1^r UNION L2^r this equality must hold true ,but I read somewhere so this equality wasn't true , so what is the conclusion ? e.g . (01+11)^r = 10+11 (LHS) now RHS will be (10+11) So I guess equality must hold true .
