For each of the following statements about regular expressions α, β and languages A, B, state whether they are true or false. Provide a one-sentence justification for each answer. i. lang((aß)*a) = lang(a(Ba)*).ii. lang((a | B)*a) = lang (3* a).iii. lang(a* ß(a | B)*) = lang((a | B)* B(a | B)*).iv. lang((a | B)*3(a | B)* | (a | B)*a(a | 3)*) = lang((a | B)+).v. If A is regular, then AR (the language formed by reversing every string in A)is also regular.

Here, each statements about regular expressions α, β and languages A, B, you are asked to determine…

i. lang((aß)*a) = lang(a(Ba)*). ii. lang((a | ß)*a) = lang(*a). ii. lang(a*ß(a | B)*) = lang((a | B)*3(a | B)*). v. lang((a | B)*ß(a | B)* | (a | B)*a(a | B)*) = lang((a | B)+). v. If A is regular, then AR (the language formed by reversing every string in A) is also regular.

i. lang((aß)a) = lang(a(Ba)). ii. lang((a | ß)a) = lang(a). ii. lang(aß(a | B)) = lang((a | B)3(a | B)). v. lang((a | B)ß(a | B) | (a | B)a(a | B)) = lang((a | B)+). v. If A is regular, then AR (the language formed by reversing every string in A) is also regular.

If false, give a counterexample (i.e. a set of values x,y that make the statement false. You must also explain why they make the statement false.) a) yvx((y > x²) → y > x) b) Vy!x(√√ 0)) d) x(x < 0⇒x² ≥y) e) \xy(x² = y² ↔ y³ = x³)
