Question

Write the following sets.
1) Set of the first five positive integers.
2) Set of multiples of which are more than 100 and less than 125
3) Set of first five cubic numbers
4) Set of digits in the Ramanujan number​

Answer 1

Given: The numbers.

To find: Write the following sets as given in question.

Solution:

• Now the sets to be written are:

            1) Set of the first five positive integers.

                      S = { 1, 2, 3, 4, 5 } .......(all are positive integers )

            2) Set of multiples of 5 which are more than 100 and less than 125

                      S = { 105, 110, 115, 120 } .......(all are multiple of 5 )

           3) Set of first five cubic numbers

                      S = { 1, 8, 27, 64, 125 }  .......(all are cubes )

           4) Set of digits in the Ramanujan number​

                      S = { 1, 7, 2, 9 } .................(all are Ramanujan numbers )

Answer:

          So all the sets are written in solution part.

Answer 2

Answer:

1.sol set of the first 5 positive integers s=(1,2,3,4,5)

2 sol s=(105,110,115,120)

3sol s=(1,8,27,64,125)

4sol s=(1,7,2,9)
