Simplify Square Root of 42896

Here we will show you two methods that you can use to simplify the square root of 42896. In other words, we will show you how to find the square root of 42896 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.

√42896 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 42896 to simplify the square root of 42896. 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 42896. The factors of 42896 are 1, 2, 4, 7, 8, 14, 16, 28, 56, 112, 383, 766, 1532, 2681, 3064, 5362, 6128, 10724, 21448, and 42896. Furthermore, the greatest perfect square on this list is 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Calculate 42896 divided by the greatest perfect square from the list of all factors of 42896. We determined above that the greatest perfect square from the list of all factors of 42896 is 16. Furthermore, 42896 divided by 16 is 2681, therefore B equals 2681.

Now we have A and B and can get our answer to 42896 in its simplest radical form as follows:

√42896 = A√B

√42896 = 4√2681

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 42896 to simplify the square root of 42896 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 42896 and then take the square root of that product. The prime factors that multiply together to make 42896 are 2 x 2 x 2 x 2 x 7 x 383. When we strip out the pairs only, we get 2 x 2 x 2 x 2 = 16 and the square root of 16 is 4. Therefore, A equals 4.

B = Divide 42896 by the number (A) squared. 4 squared is 16 and 42896 divided by 16 is 2681. Therefore, B equals 2681.

Once again we have A and B and can get our answer to 42896 in its simplest radical form as follows:

√42896 = A√B

√42896 = 4√2681
