C-02-Q016mediumsingle_mcq

$C = \{x : x$ is a positive integer and $x^2 < 18\}$ in roster form is—

a $\{1, 2, 3\}$
b $\{1, 2, 3, 4\}$
c $\{1, 2, 3, 4, 5\}$
d $\{0, 1, 2, 3, 4\}$

ব্যাখ্যা

For positive integers, $x^2 < 18$ holds when $x = 1, 2, 3, 4$ (since $4^2 = 16 < 18$ ) but fails at $x = 5$ (as $5^2 = 25$ ). Hence the set is $\{1, 2, 3, 4\}$ .
