Simplify Square Root of 21950

Here we will show you two methods that you can use to simplify the square root of 21950. In other words, we will show you how to find the square root of 21950 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.

√21950 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 21950 to simplify the square root of 21950. 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 21950. The factors of 21950 are 1, 2, 5, 10, 25, 50, 439, 878, 2195, 4390, 10975, and 21950. Furthermore, the greatest perfect square on this list is 25 and the square root of 25 is 5. Therefore, A equals 5.

B = Calculate 21950 divided by the greatest perfect square from the list of all factors of 21950. We determined above that the greatest perfect square from the list of all factors of 21950 is 25. Furthermore, 21950 divided by 25 is 878, therefore B equals 878.

Now we have A and B and can get our answer to 21950 in its simplest radical form as follows:

√21950 = A√B

√21950 = 5√878

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 21950 to simplify the square root of 21950 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 21950 and then take the square root of that product. The prime factors that multiply together to make 21950 are 2 x 5 x 5 x 439. When we strip out the pairs only, we get 5 x 5 = 25 and the square root of 25 is 5. Therefore, A equals 5.

B = Divide 21950 by the number (A) squared. 5 squared is 25 and 21950 divided by 25 is 878. Therefore, B equals 878.

Once again we have A and B and can get our answer to 21950 in its simplest radical form as follows:

√21950 = A√B

√21950 = 5√878
