Question

Write the following sets in roster form.
(1) A = {x:x is a natural number greater than 50 but smaller than 100}
B = {x : x is an integer, r2 = 4}
D= {x:x is a letter in the word "LOYAL"}​

Answer 1

$\red{1 )A = \{ x:x\:is \:a \: natural \:number \: greater}\\\red{\:than \: 50 \: but \: smaller \:than \: 100 \}}$

$\green {A = \{51,52,53,54,55,\cdot \cdot \cdot , 98,99\}}$

$\red{ 2) B = \{ x :x \:is \: an \: integer \: , x^{2} = 4 \} }$

$\green { B = \{ -2, 2 \} }$

$\red{ D = \{ x : x \: is \: a \: letter \: in \:the \: word \: "LOYAL" \} }$

$\green { D = \{ L,O,A,Y \}}$
