It is: (5*10)-25 = 25

5 + 20 = 25
The square root of 25 is 5 The square root of 36 is 6 So the square root of 27 is between 5 and 6, and closer to 5 than to 6. Try 5.12 = 52 + 2*5*0.1 + 0.12 = 25 + 10*.1 + a little bit = around 26 5.22 = 25 +10*.2 + a little bit = 27 + a little so that looks good. Then approx value for 8 + sqrt(27) = 8 + 5.2 = 13.2 The precise answer is 13.196 so the approximation is only 0.03% out.
