Question

Answer 1

Answer:

(MUN)={3,4,5,6,7,8,9,10}

Step-by-step explanation:

The union of two sets is a set containing all elements that are in A or in B (possibly both). Thus, we can write x∈(A∪B) if and only if (x∈A) or (x∈B). Note that A∪B=B∪A.

(MUN)={3,4,5,6,7,8,9,10}

Answer 2

Step-by-step explanation:

M={3,4,5,6,7,8,9,10}

N={6,7,8,9}

M U N=?

soution: we know what is the meaning of union

if you don't know then don't worry I am telling you

union = group of elements ( sum of all elements/objects)

now A.T.Q

M U N = {3,4,5,6,7,8,9,10} ✓
