## 4. How do you find the square root of 20? - Socratic

31 Aug 2016 · Since 20 is roughly halfway between 42 and 52 , its square root is approximately 92 - halfway between 4 and 5 . In fact, we find: 92 ...

Find approximation: sqrt(20) ~~ 2889/646 ~~ 4.472136 The prime factorisation is: 20 = 2^2*5 Hence: sqrt(20) = 2sqrt(5) This is an irrational number between 4 and 5 since: 4^2 = 16 < 20 < 25 = 5^2 It is not expressible as an exact fraction, but we can find rational approximations... Since 20 is roughly halfway between 4^2 and 5^2, its square root is approximately 9/2 - halfway between 4 and 5. In fact, we find: 9^2 = 81 = 80+1 = 20*2^2 + 1 which is in Pell's equation form: p^2 = n q^2 + 1 with n = 20, p = 9 and q = 2 That means that we can deduce the continued fraction for sqrt(20) from the continued fraction for 9/2... 9/2 = 4+1/2 = [4;2] Hence: sqrt(20) = [4;bar(2,8)] = 4+1/(2+1/(8+1/(2+1/(8+1/(2+1/(8+...)))))) To get a good approximation for sqrt(20) truncate this continued fraction early, just before an '8'... For example: sqrt(20) ~~ [4;2,8,2,8,2] = 4+1/(2+1/(8+1/(2+1/(8+1/2)))) = 2889/646 ~~ 4.472136 From a calculator: sqrt(20) ~~ 4.472135955
