1. Find the square of a number containing repeated 1

Steps involved:

Step-1: Count the digit, assume number of Digit=n

Step-2: Now write the number starting from 1 to till n

Step-3: and just decrease the number to till 1

Example 1: Find the Square of 111.

Solution: First we Count the digit, 1 is repeated 3 times so total number of digit is=3

Now we write the number from 1 to 3, means- 123

Now decrease the umber from 3 to 1, means - 21 (because 3 is already written)

so answer is = 12321

Example 2: Find the Square of 11111.

Solution: First we Count the digit, 1 is repeated 5 times so total number of digit is=5

Now we write the number from 1 to 5, means- 12345

Now decrease the umber from 5 to 1, means - 4321 (because 5 is already written)

so answer is = 123454321

2. Find the square of a number containing repeated 3

Steps involved:

Step-1: Count the digit, assume number of Digit=n

Step-2: then write (n-1)times 1 then 0

Step-3: again write (n-1)times 8 then 9

Example 1: Find the Square of 33333.

Solution: First we Count the digit, 3 is repeated 5 times so total number of digit is=5, it means n=5.

Now we write (5-1=4) times 1 then 0. it means: 11110

Now (5-1=4)times 8 then 9. it means: 88889

Combine together and answer is = 1111088889
