Question

write the following in roster form: A= {x: x is an even natural number, x^2 <40),​

Answer 1

Answer:

{2,4,6}

Step-by-step explanation:

1. take even natural numbers which are 2 , 4 ,6 ,...

then substitute these values 1 by 1 in the equation x^2<40 and check,

put   x = 2

$2^{2} <40$

4< 40  true

then check   x = 4

$4^{2} <40$

16<40  true

check  x=6

$6^{2}<40$

36< 40  true

hence the roaster form :A={2,4,6}
