Which value is a reasonable approximation of the square root of 67?
8.185
Is 4.5 the square root of 21?
4.6 is a better approximation to the square root of 21.
What is the formula to find out the square root of 20?
The square root of 20 is an irrational number that can be expressed as 2 times square root of 5
Which value is a reasonable approximation of 8 plus the square root of 27?
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.
What is the square root of 6.35?
