Simplify Square Root of 38961

Here we will show you two methods that you can use to simplify the square root of 38961. In other words, we will show you how to find the square root of 38961 in its simplest radical form using two different methods.

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.

√38961 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 38961 to simplify the square root of 38961. This is how to calculate A and B using this method:

A = Calculate the square root of the greatest perfect square from the list of all factors of 38961. The factors of 38961 are 1, 3, 9, 13, 27, 37, 39, 81, 111, 117, 333, 351, 481, 999, 1053, 1443, 2997, 4329, 12987, and 38961. Furthermore, the greatest perfect square on this list is 81 and the square root of 81 is 9. Therefore, A equals 9.

B = Calculate 38961 divided by the greatest perfect square from the list of all factors of 38961. We determined above that the greatest perfect square from the list of all factors of 38961 is 81. Furthermore, 38961 divided by 81 is 481, therefore B equals 481.

Now we have A and B and can get our answer to 38961 in its simplest radical form as follows:

√38961 = A√B

√38961 = 9√481

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 38961 to simplify the square root of 38961 to its simplest form possible. This is how to calculate A and B using this method:

A = Multiply all the double prime factors (pairs) of 38961 and then take the square root of that product. The prime factors that multiply together to make 38961 are 3 x 3 x 3 x 3 x 13 x 37. When we strip out the pairs only, we get 3 x 3 x 3 x 3 = 81 and the square root of 81 is 9. Therefore, A equals 9.

B = Divide 38961 by the number (A) squared. 9 squared is 81 and 38961 divided by 81 is 481. Therefore, B equals 481.

Once again we have A and B and can get our answer to 38961 in its simplest radical form as follows:

√38961 = A√B

√38961 = 9√481
