Simplify Square Root of 9900

Here we will show you two methods that you can use to simplify the square root of 9900. In other words, we will show you how to find the square root of 9900 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.

√9900 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 9900 to simplify the square root of 9900. 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 9900. The factors of 9900 are 1, 2, 3, 4, 5, 6, 9, 10, 11, 12, 15, 18, 20, 22, 25, 30, 33, 36, 44, 45, 50, 55, 60, 66, 75, 90, 99, 100, 110, 132, 150, 165, 180, 198, 220, 225, 275, 300, 330, 396, 450, 495, 550, 660, 825, 900, 990, 1100, 1650, 1980, 2475, 3300, 4950, and 9900. Furthermore, the greatest perfect square on this list is 900 and the square root of 900 is 30. Therefore, A equals 30.

B = Calculate 9900 divided by the greatest perfect square from the list of all factors of 9900. We determined above that the greatest perfect square from the list of all factors of 9900 is 900. Furthermore, 9900 divided by 900 is 11, therefore B equals 11.

Now we have A and B and can get our answer to 9900 in its simplest radical form as follows:

√9900 = A√B

√9900 = 30√11

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 9900 to simplify the square root of 9900 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 9900 and then take the square root of that product. The prime factors that multiply together to make 9900 are 2 x 2 x 3 x 3 x 5 x 5 x 11. When we strip out the pairs only, we get 2 x 2 x 3 x 3 x 5 x 5 = 900 and the square root of 900 is 30. Therefore, A equals 30.

B = Divide 9900 by the number (A) squared. 30 squared is 900 and 9900 divided by 900 is 11. Therefore, B equals 11.

Once again we have A and B and can get our answer to 9900 in its simplest radical form as follows:

√9900 = A√B

√9900 = 30√11
