Simplify Square Root of 81995

Here we will show you two methods that you can use to simplify the square root of 81995. In other words, we will show you how to find the square root of 81995 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.

√81995 = A√B

Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 81995 to simplify the square root of 81995. 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 81995. The factors of 81995 are 1, 5, 23, 31, 115, 155, 529, 713, 2645, 3565, 16399, and 81995. Furthermore, the greatest perfect square on this list is 529 and the square root of 529 is 23. Therefore, A equals 23.

B = Calculate 81995 divided by the greatest perfect square from the list of all factors of 81995. We determined above that the greatest perfect square from the list of all factors of 81995 is 529. Furthermore, 81995 divided by 529 is 155, therefore B equals 155.

Now we have A and B and can get our answer to 81995 in its simplest radical form as follows:

√81995 = A√B

√81995 = 23√155

Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 81995 to simplify the square root of 81995 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 81995 and then take the square root of that product. The prime factors that multiply together to make 81995 are 5 x 23 x 23 x 31. When we strip out the pairs only, we get 23 x 23 = 529 and the square root of 529 is 23. Therefore, A equals 23.

B = Divide 81995 by the number (A) squared. 23 squared is 529 and 81995 divided by 529 is 155. Therefore, B equals 155.

Once again we have A and B and can get our answer to 81995 in its simplest radical form as follows:

√81995 = A√B

√81995 = 23√155
