Question

how to find square root of 2 = 1.414?

Answer 1

$\sqrt{2 } = 1.414$

Answer 2

u have to learn these ....
but u can assume it's value by root 4 is equal to 2
and root 1 is equal to 1...so u can think by urself that root 2 lies somewhere between 1 and 2.
as root 2 is greater then 1 its value will be greater than 1.
root 4 -root 1 =1
there is two numbers in between so decide by two.that us 1/2=.5
so ur ans may be 1.5...u can assume ...
or else u have to learn atleast 10 root values
