Simplify Square Root Of 98

Simplify Square Root of 98 Here we will show you two methods that you can use to simplify the square root of 98. In other words, we will show you how to find the square root of 98 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. √98 = A√B Greatest Perfect Square Factor Method The Greatest Perfect Square Factor Method uses the greatest perfect square factor of 98 to simplify the square root of 98. 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 98. The factors of 98 are 1, 2, 7, 14, 49, and 98. Furthermore, the greatest perfect square on this list is 49 and the square root of 49 is 7. Therefore, A equals 7. B = Calculate 98 divided by the greatest perfect square from the list of all factors of 98. We determined above that the greatest perfect square from the list of all factors of 98 is 49. Furthermore, 98 divided by 49 is 2, therefore B equals 2. Now we have A and B and can get our answer to 98 in its simplest radical form as follows: √98 = A√B √98 = 7√2 Double Prime Factor Method The Double Prime Factor Method uses the prime factors of 98 to simplify the square root of 98 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 98 and then take the square root of that product. The prime factors that multiply together to make 98 are 2 x 7 x 7. When we strip out the pairs only, we get 7 x 7 = 49 and the square root of 49 is 7. Therefore, A equals 7. B = Divide 98 by the number (A) squared. 7 squared is 49 and 98 divided by 49 is 2. Therefore, B equals 2. Once again we have A and B and can get our answer to 98 in its simplest radical form as follows: √98 = A√B √98 = 7√2 Simplify Square Root Please enter another square root in the box below for us to simplify. √ Simplify Square Root of 99 Here is the next square root on our list that we have simplifed for you.
