Question

Write the following set in roster form:
B = {x:x belongs to I and x^2 < 20 }

Answer 1

Step-by-step explanation:

B = { 0, 1, 4, 16}

( in place of x integers will be written and the members will be square, which will be less than 20, so.0 square = 0, 1 & -1 square = 1, so on till 16 for -4 and 4 - please note 5 and -5 is greater than 25 so it will not be a member of the given set)

I hope it helps
