91 is a Prime number, so you have to use a calculator, but if you had a number such as 99 use this method: divide 99 by a number that goes into it evenly, such as 9, now you have 9 and 11, 11 is prime so you set it aside, leaving 9. now divide 9 by a number, 3 is the only one in this situation, so you have two 3's. once you only have prime numbers put them with likes, so now you have 3,3,11, all numbers that have a pair you take out one and cross off that pair, leaving those without under the radical (square root). in this case the answer is 3 multiplied by the square root of 11. in order to find the square root of any prime number, a calculator is required.
