It is 5.57 (approximately)

#sqrt31 = 5.567764363# numerically.

You can accept that it is #5.57#

#sqrt31~~5.568#

Since #31# is a prime number, its square root doesn't evaluate to an integer. We can approximate it with the next closest perfect squares

#sqrt25<=sqrt31<=sqrt36# or

#5<=sqrt31<=6#

We know the principal root of #31# is between #5# and #6#, but we can get a better estimate with the use of a calculator. We get

#sqrt31~~5.568#

Hope this helps!
