Question

plz define null set, equal set, equivalent set,finite set,infinite set​

Answer 1

null set is a set that can be covered by a countable union of intervals of arbitrarily small total length.

Equal sets are the Sets that have precisely the same elements. They don't have to be in the same order. Example: {1,2,3,4} and {3,4,2,1} are equal.

Equal sets are Two sets that are equivalent if they have the same cardinality or the same number of elements.

An infinite set is a set whose elements can not be counted. An infinite set is one that has no last element.

Answer 2

Hi,your answer is

Null set is the set where there is no element..Like A={}

Equal set are those set where the elements are same..Such as A={1,2,3} and B={3,1,2}.They are equal set.

Equivalent set are those set where cardinal number of two sets are equal.Like as A={1,2,3} and B={3,1,2}..They have same cardinal number.So,they are equivalent

set.

Set having countable number of element is called finite Set.

Set having uncountable number of element is called an infinite set..

HOPE IT HELP YOU A LOT....
