Simplify Square Root of 20991

What is the square root of 20991 in its simplest radical form? To be more specific, we have created an illustration below showing what we want to calculate. Our goal is to make "A" outside the radical (√) as large as possible, and "B" inside the radical (√) as small as possible.

√20991 = A√B

Unfortunately, the square root of 20991 cannot be simplified. Thus, here is the answer to the square root of 20991 in its simplest form:

√ 20991 = √ 20991

Here are two different methods we used to determine why the square root of 20991 cannot be simplified.

1) To be able to simplify the square root of 20991, one of the factors of 20991 other than 1 must be a perfect square. The factors of 20991 are 1, 3, 6997, and 20991. Since none of these factors are perfect squares, the square root of 20991 cannot be simplified.

2) To be able to simplify the square root of 20991, all the prime factors of 20991 cannot be unique. When we did prime factorization of 20991, we found that 3 x 6997 equals 20991. Since all the prime factors are unique, the square root of 20991 cannot be simplified.
