3.16227766 which is about 3.2
1.4142 is an approximation for the square root of 2.
The answer is 12, since 12 times 12 equals 144- that is, 12 squared is 144. The square root of a number is that number which when squared gives the given number. Unless the number is a square, its square root will be a decimal approximation.
Impossible to give the "complete" square root as the number is indefinite... a good approximation is 1.77245385.
You can get a decimal approximation with a calculator, with Excel, etc. But if you want to keep it as a square root, the "standard form" is considered to be one that has no square roots in the denominator. In this case, to get rid of the square root in the denominator, you multiply both numerator and denominator by the square root of 5, with the following result: 3 / root(5) = 3 root(5) / root(5) x root(5) = 3 root(5) / 5 That is, three times the square root of 5, divided by 5.
