Squaring of a number ending with 25.
We all know about the Squaring of number ending in 5 .Here we will learn one more simple trick/shortcut.
Here comes the other method of performing squaring of a number ending in 25.
Rule :- Result will be consisting of two parts lets say LHS and RHS.
#LHS part can be obtained by simple steps.
#RHS part will be always 25 squared =625.
#LHS part :-
Splitting the given number into two parts …such that the there are two parts.. one contain 25 n other nt. Affix to number without 25. eg.
LHS :- p5 ×p .Here 5 is just affixed to the number p n multiplied by p.
Now., Lets take example to understand the method.
Example-1:- 225 ^2 = ???
25×2 = 50 》 》 LHS part obtained. 🙂
RHS part always 625.
Therefore, 225 squared equals 50625.
Let’s take another example,
85×8 =680》》》 LHS part of result.
RHS will be always 625
Therefore, 825 squared will be 680625.
It is simple.
