Simplify Square Root of 42496

Here we will show you two methods that you can use to simplify the square root of 42496. In other words, we will show you how to find the square root of 42496 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.

√42496 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 42496 to simplify the square root of 42496. 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 42496. The factors of 42496 are 1, 2, 4, 8, 16, 32, 64, 83, 128, 166, 256, 332, 512, 664, 1328, 2656, 5312, 10624, 21248, and 42496. Furthermore, the greatest perfect square on this list is 256 and the square root of 256 is 16. Therefore, A equals 16.

B = Calculate 42496 divided by the greatest perfect square from the list of all factors of 42496. We determined above that the greatest perfect square from the list of all factors of 42496 is 256. Furthermore, 42496 divided by 256 is 166, therefore B equals 166.

Now we have A and B and can get our answer to 42496 in its simplest radical form as follows:

√42496 = A√B

√42496 = 16√166

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 42496 to simplify the square root of 42496 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 42496 and then take the square root of that product. The prime factors that multiply together to make 42496 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 83. When we strip out the pairs only, we get 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 256 and the square root of 256 is 16. Therefore, A equals 16.

B = Divide 42496 by the number (A) squared. 16 squared is 256 and 42496 divided by 256 is 166. Therefore, B equals 166.

Once again we have A and B and can get our answer to 42496 in its simplest radical form as follows:

√42496 = A√B

√42496 = 16√166
