Write the following sets by listing its elements.

A = {n ∈ \mathbb{N} : n > 10}

B = {m ∈ \mathbb{Z} : \left | m \right | ≤ 4}

C={x∈\mathbb{R}: x2+2x+2=0}

D={x∈\mathbb{R}: x2+2=0}

Answer:

A = {11, 12, 13, 14, 15, ....}

B = {-4, -3, -2, -1, 0, 1, 2, 3, 4}

C = {}

D = {}

Step-by-step explanation:

A is just natural numbers greater than 10 so it's 11, 12, and so on.

B is an integer between -4 and 4 inclusively. |m| ≤ 4 is same as -4 ≤ m ≤ 4

C and D is quadratic equation with no real solution, and since the set must be in real numbers, C and D are both empty set.
