Simplify Square Root of 12942

Here we will show you two methods that you can use to simplify the square root of 12942. In other words, we will show you how to find the square root of 12942 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.

√12942 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 12942 to simplify the square root of 12942. 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 12942. The factors of 12942 are 1, 2, 3, 6, 9, 18, 719, 1438, 2157, 4314, 6471, and 12942. Furthermore, the greatest perfect square on this list is 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Calculate 12942 divided by the greatest perfect square from the list of all factors of 12942. We determined above that the greatest perfect square from the list of all factors of 12942 is 9. Furthermore, 12942 divided by 9 is 1438, therefore B equals 1438.

Now we have A and B and can get our answer to 12942 in its simplest radical form as follows:

√12942 = A√B

√12942 = 3√1438

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 12942 to simplify the square root of 12942 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 12942 and then take the square root of that product. The prime factors that multiply together to make 12942 are 2 x 3 x 3 x 719. When we strip out the pairs only, we get 3 x 3 = 9 and the square root of 9 is 3. Therefore, A equals 3.

B = Divide 12942 by the number (A) squared. 3 squared is 9 and 12942 divided by 9 is 1438. Therefore, B equals 1438.

Once again we have A and B and can get our answer to 12942 in its simplest radical form as follows:

√12942 = A√B

√12942 = 3√1438
