Simplify Square Root of 36400

Here we will show you two methods that you can use to simplify the square root of 36400. In other words, we will show you how to find the square root of 36400 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.

√36400 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 36400 to simplify the square root of 36400. 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 36400. The factors of 36400 are 1, 2, 4, 5, 7, 8, 10, 13, 14, 16, 20, 25, 26, 28, 35, 40, 50, 52, 56, 65, 70, 80, 91, 100, 104, 112, 130, 140, 175, 182, 200, 208, 260, 280, 325, 350, 364, 400, 455, 520, 560, 650, 700, 728, 910, 1040, 1300, 1400, 1456, 1820, 2275, 2600, 2800, 3640, 4550, 5200, 7280, 9100, 18200, and 36400. Furthermore, the greatest perfect square on this list is 400 and the square root of 400 is 20. Therefore, A equals 20.

B = Calculate 36400 divided by the greatest perfect square from the list of all factors of 36400. We determined above that the greatest perfect square from the list of all factors of 36400 is 400. Furthermore, 36400 divided by 400 is 91, therefore B equals 91.

Now we have A and B and can get our answer to 36400 in its simplest radical form as follows:

√36400 = A√B

√36400 = 20√91

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 36400 to simplify the square root of 36400 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 36400 and then take the square root of that product. The prime factors that multiply together to make 36400 are 2 x 2 x 2 x 2 x 5 x 5 x 7 x 13. When we strip out the pairs only, we get 2 x 2 x 2 x 2 x 5 x 5 = 400 and the square root of 400 is 20. Therefore, A equals 20.

B = Divide 36400 by the number (A) squared. 20 squared is 400 and 36400 divided by 400 is 91. Therefore, B equals 91.

Once again we have A and B and can get our answer to 36400 in its simplest radical form as follows:

√36400 = A√B

√36400 = 20√91
