I came across this trick in vedic maths. I would like to share it.
FIND THE SQUARES
a) 44444^2=
b) 555^2=
c) 99999^2=
d) 66666^2=
now we can observe the repetition of a digit in all these numbers. In such pattern we can use the duplex method to find the square.
a) 44444^2=
· count the 4's
· it comes for 5 times in the numbers
· so now in ans. write down square of 4 that is 16 as the last part of the ans.
· than go on writing table of 16 for 5 times (duplex of the numbers will give us the table of 16)
· than reverse of the table of 16 up to 1
· 16/32/48/64/80/64/48/32/16
· as we know tens digits are carry overs so our ans. is
· 1975269136
b) 555^2=25/50/75/50/25=308025
what if the numbers are
a)1212^2
b)1414^2
a)2121^2
Do anyone know the answer of this.
