To approximate the square root of any non perfect square number, you can perform a series of steps:
# Guess # Divide
# Average
For example, let's use the number 20.
# Guess - the square root of 20 is around 4. # Divide - 20 / 4 = 5 # Average - The average of 4 (our guess) and 5 (our quotient) is 4.5 # Now divide 20 by 4.5 = about 4.44 # Average 4.44 (our quotient) and 4.5 (our last average) = 4.472 # Repeat as many times as necessary to achieve a sufficient approximation.
