Here we will show you two methods that you can use to simplify the square root of 1775. In other words, we will show you how to find the square root of 1775 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.
√1775 = A√B
Greatest Perfect Square Factor Method
The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 1775 to simplify the square root of 1775. 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 1775. The factors of 1775 are 1, 5, 25, 71, 355, and 1775. Furthermore, the greatest perfect square on this list is 25 and the square root of 25 is 5. Therefore, A equals 5.
B = Calculate 1775 divided by the greatest perfect square from the list of all factors of 1775. We determined above that the greatest perfect square from the list of all factors of 1775 is 25. Furthermore, 1775 divided by 25 is 71, therefore B equals 71.
Now we have A and B and can get our answer to 1775 in its simplest radical form as follows:
√1775 = A√B
√1775 = 5√71
Double Prime Factor Method
The Double Prime Factor Method uses the prime factors of 1775 to simplify the square root of 1775 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 1775 and then take the square root of that product. The prime factors that multiply together to make 1775 are 5 x 5 x 71. 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 1775 by the number (A) squared. 5 squared is 25 and 1775 divided by 25 is 71. Therefore, B equals 71.
Once again we have A and B and can get our answer to 1775 in its simplest radical form as follows:
√1775 = A√B
√1775 = 5√71
