Squaring of a number ending in 05

Squaring of a number ending in 05

We have observed and learned the method of squaring of a number of number ending in 5 in our previous post.
   What if the number ends with 05
Like 105 ,205, 705…?

  • Square the number other than 05.
  •Find the square of the first part of                  the given number.
• Affix /Place the first part of number after the square of number part.
•Atlast affix 05^2 =025 at the end .

Consider following examples.

Example 1:-
             205^2 = (2/05)^2
Example 2:-
Example 3:-

Let’s take a larger number this time.
         Example 4:-
                  1105^2 =
                            =   11^2/11/025
                             =1221025 ( Here 11 is greater 10 therefore push it to next block).
        Example 5:-
                          1305^2 =
                            =   13^2/13/025

It is simple.
