Answer 1

Answer:

1.set is a well defined collection of objects is called a set.

2.{i,n,d,a} 2). {m,a,t,h,e,i,c,s}

3.1) {PUQUR}

pUq = {1,2,5,7,9}U{2,3,5,9}

= {1,2,3,5,7,9}

then pUqUr= {1,2,3,5,7,9}U{3,4,5,7,9}

={1,2,3,4,5,7,9}....

2) PnQnR=

pnq = {2,5,9}

PnQnR= {2,5,9}n{3,4,5,7,9}

= {5,9}......

4. RATIONAL NUMBER:.

the p/q form of a number when q#0 and p,q are integers.

5. surds means irrational numbers.
