VJ’s Power Lemma Let ( Lemma: - ) = ( 5 ) 𝐻 𝑈
Where
Then for
𝐻 𝑎𝑛−1 (2𝑛 − 5) (𝑘𝑛−2)𝑘=𝑎𝑘= 1
It is useful in computing nth root of perfect n
th power. Application :-
Power of Number Ending with 5
Let 5 is the number ending with 5, then
( )2 = ( 2 ( )) 2 5 25
= 2 ( ) 25 (i.e. Append 25 to 2 )
( )3 = ( 3 ( 2 5 )) 𝑎 𝑎500

Where Sum of natural numbers up to 𝑎 𝑎
( )4 = ( 4 ( 3 5 𝑎 )) (2 6 ) 25
Where 𝑎 Sum of square of natural numbers up to 2 𝑎
