Use the given sets to find X n (Y U Z). U = {a, b, c, d,...,x, y,z}
X = {n, u, m, b, e, r}
Y = {b, r, e, a, t, h}
Z = {I, a, u, g, h, t, e, r}

With Y = {b, r, e, a, t, h} and Z = {l, a, u, g, h, t, e, r}, their union is

Y U Z = {b, r, e, a, t, h, l, u, g}

Then with X = {n, u, m, b, e, r}, the intersection with Y U Z is

X ∩ (Y U Z) = {u, b, e, r}

step-by-step explanation:

it's 15

the discriminant is 64 + 4*1*12 = 112

this is prime.
