120The answer is 120.
No, it is not. For it to be a perfect square, the square root of it would have to be an integer, but √120 ≈ 10.954. 100 and 121 are perfect squares nearest to 120. ■

10.95445Square Root of 120The square root of 120 is 10.954, but it is easier to say "square root of 120." You could also reduce itSQRT(120) = SQRT(12) * SQRT(10) = [SQRT(4)*SQRT(3)] * [SQRT(5) * SQRT(2)] =2 * SQRT(3) * SQRT(5) * SQRT(2)It is common to reduce large numbers under the radical to a string of factors having prime numbers under the radicals.
