How do you simplify # sqrt961#?

Answer 1

#sqrt(961) = sqrt(31^2) = 31#

Factor the number under the square root. For a large number like this one you need to test all the prime numbers until you reach the square root or the nearest number to it.

In this case #961 = 31^2# #31# is a prime number so there are no other simplifications

#sqrt(961) = sqrt(31^2) = 31#
