Class 9th math Review Exercise 3 solution english PCTB

Question 2: Write each of the following sets in tabular forms:

\((iii)\) \(\;\) \(\{x|x=11n, n\in W \wedge n<11\} \)

Solution:

Tabular Form:

\(\{0,11,22,33,44,55,66,77,88,99,110\}\)


Explanation:

\(x=11n+1\) and \(\{n \in W \land n<11\}\) which means that \(n\in \{0,1,2,3,4,5,6,7,8,9,10\}\)

\(11(0)=0\)

\(11(1)=11\)

\(11(2)=22\)

\(11(3)=33\)

\(11(4)=44\)

\(11(5)=55\)

\(11(6)=66\)

\(11(7)=77\)

\(11(8)=88\)

\(11(9)=99\)

\(11(10)=110\)
