The fоllоwing expressiоns represents а stаtement аbout all the integers (Z). Using p(x) for 'x is prime', q(x, y) for 'x = y2 ', and t(x, y) for 'x = y', determine which expressions represent true statements and which represent false statements (justify your answer to get the full points, as just writing true or false is not enough for any points).a) ∨x∈Z(∃y∈Z(q(x, y)∨p(x)))b) ∃z∈Z(∃x∈Z(∃y∈Z(p(x)∧p(y)∧¬t(x, y))))
