How do you turn the square root of 405 into number or a decimal?

Best option is to use a calculator. Failing that, use the Newton-Raphson method which entails making a guess at the answer and then improving on it. Repeating the procedure should lead to a better estimate at each stage. To start with, if you want to find the square root of 405, define f(x) = x2 - 405. Then finding the square root of 405 is equivalent to solving f(x) = 0. Let f'(x) = 2x. This is the derivative of f(x) but you do not need to know that to use the N-R method. Start with x0 as the first guess. Then let xn+1 = xn - f(xn)/f'(xn) for n = 0, 1, 2, … After a few iterations, xn will be very close to the required square root. If you start with 20, whose square is 400, the second iteration gives a result that is accurate to 8 decimal places.
