Problem Solving (PS) | Re: A={x| x^2>9}, B={x| 1

A={x| x^2>9} - This set contains all positive numbers greater than x=3
B={x| 1<x<16} - This set contains all positive number from x=1.1 to x=15.9
C={x| x^2<25} - This set contains all positive numbers from x=-4.9 to x=4.9

If we have been asked to find the intersection of the three sets,
we need to find the common numbers which is 3<|x|<5(Option B)

P.S if x is an integer, then Option E is the correct answer.
