Question: Convert the following formulas into equivalent Skolem normal form: ((x)P(x) => (x)(y)(z)Q(x,y,z)) z(xQ(x,z) v xP(x)) => (xP(x) ^ xzQ(z,x)) xyP(x,y) v y(Q(y) => zR(z))

Convert the following formulas into equivalent Skolem normal form:

((x)P(x) => (x)(y)(z)Q(x,y,z))

z(xQ(x,z) v xP(x)) => (xP(x) ^ xzQ(z,x))

xyP(x,y) v y(Q(y) => zR(z))
