Question

Express the given sets in roster form:

(v) S = {Squares of first eight whole numbers}.

Answer 1

Step: Expressing set S in roster form

In roster form, the elements of the set are written inside a pair of curly braces and are separated by commas.

Given, S = {Squares of first eight whole numbers}

First eight whole numbers are $0,1,2,3,4,5,6$ and $7.$

And their squares are $0^2=0,1^2=1,2^2=4,3^2=9,4^2=16,5^2=25,$
$6^2=36$ and $7^2=49.$

Hence, the roster form of set is
$S$ = {0, 1, 4, 9, 16, 25, 36, 49}.
