Simplify Square Root of 81922

What is the square root of 81922 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.

√81922 = A√B

Unfortunately, the square root of 81922 cannot be simplified. Thus, here is the answer to the square root of 81922 in its simplest form:

√ 81922 = √ 81922

Here are two different methods we used to determine why the square root of 81922 cannot be simplified.

1) To be able to simplify the square root of 81922, one of the factors of 81922 other than 1 must be a perfect square. The factors of 81922 are 1, 2, 40961, and 81922. Since none of these factors are perfect squares, the square root of 81922 cannot be simplified.

2) To be able to simplify the square root of 81922, all the prime factors of 81922 cannot be unique. When we did prime factorization of 81922, we found that 2 x 40961 equals 81922. Since all the prime factors are unique, the square root of 81922 cannot be simplified.
