Question

write the set {x:x€R and 0<x<7} as an interval​

Answer 1

Answer:

{x : x ∈ R and 0 < x < 7} = (0 7)

Step-by-step explanation:

We have,

A = {x : x ∈ R and 0 < x < 7}

Now, if we were to try write these elements, then it would take forever because there are an infinite terms between two natural numbers, and they are all a part of Real numbers.

Hence,

{x : x ∈ R and 0 < x < 7} = (0 7)

where 0 and 7 is not included.

Hope it helped and believing you understood it........All the best
