Here we will show you two methods that you can use to simplify the square root of 68725. In other words, we will show you how to find the square root of 68725 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.
√68725 = A√B
Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 68725 to simplify the square root of 68725. 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 68725. The factors of 68725 are 1, 5, 25, 2749, 13745, and 68725. Furthermore, the greatest perfect square on this list is 25 and the square root of 25 is 5. Therefore, A equals 5.
B = Calculate 68725 divided by the greatest perfect square from the list of all factors of 68725. We determined above that the greatest perfect square from the list of all factors of 68725 is 25. Furthermore, 68725 divided by 25 is 2749, therefore B equals 2749.
Now we have A and B and can get our answer to 68725 in its simplest radical form as follows:
√68725 = A√B
√68725 = 5√2749
Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 68725 to simplify the square root of 68725 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 68725 and then take the square root of that product. The prime factors that multiply together to make 68725 are 5 x 5 x 2749. 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 68725 by the number (A) squared. 5 squared is 25 and 68725 divided by 25 is 2749. Therefore, B equals 2749.
Once again we have A and B and can get our answer to 68725 in its simplest radical form as follows:
√68725 = A√B
√68725 = 5√2749
