Question

Write the following sets in Roster form
(i) $A=\{x:x\in N,2<X\le 10\}$
(ii) $B=\{x:x\in Z,-\frac{1}{2}<X<\frac{11}{2}\}$
(iii) $C=$ { $x:x$ is a prime number and a divisor of 6 }
(iv) $X=$ { $x:x=2^n,n\in N$ and $n\le 5$}
(v) $M=\{x:x=2y-1,y\le 5,y\in W\}$
(vi) $P=$ { $x:x$ is an integer, $x^2\le 16$ }

Answer 1

(i) $A=\{3,4,5,6,7,8,9,10\}$
(ii) $B=\{0,1,2,3,4,5\}$
(iii) $C=\{2,3\}$
