To simplify a square root start by dividing the square root by the smallest prime number possible for example if youre trying to find the square root of 98 the smallest prime number possible is 2 if you divide 98 by 2 you get 49 then rewrite the square root as a multiplication problem under the square root sign. Roots are nice but we prefer dealing with regular numbers as much as possible so for example instead of 4 we prefer dealing with 2 what about roots that arent equal to an integer like 20 still we can write 20 as 45 and then use known properties to write 45 as 45 which is 25 we simplified 20. Worksheet simplifying radicals the free calculator will solve any square root even negative ones and you can mess around with decimals too the square root calculator below will reduce any square root to its simplest radical form as well as provide a brute force rounded approximation of any real or imaginary square root. Simplifying square roots to simplify a square root make the number inside the square root as small as possible but still a whole number example 12 is simpler as 23 get your calculator and check if you want they are both the same value here is the rule when a and b are not negative
