I want proof of this statement
"every subset of a null set is also a null set"...
Where Null set is a set whose measure is 0

One of the conditions for a measure, m, is that if then .
Thanks a lot
I want to ask another thing related to it that how can we prove
Phy belongs to Rn
Where Rn denotes all null subsets of algebra R
What do you mean by "Phy"?
greek work phy means null or empty...

That is a letter of the Greek alphabet it is not a Greek word, much less a work.
In all the treatments of measure that I have seen the fact is part of the definition of measure.
Sorry for the typo mistake
In any case the empty set is a subset of every set and certainly has measure 0, therefore is in Rn.
