Question

how root 2 is equal to 1.414

Answer 1

there is a method to find the square root of a given number

as you can see in the picture above

first put zeroes twice the number of decimal places to which you want your answer, after the number after putting a decimal

start making pairs of two digits from the right side(doesn't matter if there is a single number at the end)

start dividing the pair/digit at the begining
the divisor must be equal to the quetient

for the next pair add the quetient and the divisor and increase its place value by one place and now do the same with the digit at ones place
