Question

Write in roster form?
x:x=n^2, n∈N &x<30?​

Answer 1

The rooster form is { 1,4,9,16,25 }

Answer 2

We have to find natural number x whose square is smaller than 30.

So, 1 , 2 , 3 , 4 and 5 are the numbers whose square is smaller that 30.

So, in place of n we can place these numbers.

Roster form :

{ 1 , 4 , 9 , 16 , 25 }

As we have to put the value of n and find the value of x to make a set.
