Answer:
I am giving you a short cut formula which gives approximate value of square root
√P = √Q + (P-Q)/2√Q
Where P is the number whose square root is required
Here √P=√3
Q is the nearby perfect square like Q = 4 here
√P = √3 & √Q =√4=2
√P = √Q + (P-Q)/2√Q = 2 + (3-4)/2(√4) = 2 + (-1/4) =2 –(1/4)=2 -.25 = 1.75
This is approximate value
By calculator √3=1.732…
