Express in simplest radical form.
√28
√28 can be simplified as 2√7
To express √28 in simplest radical form, we can simplify the number inside the square root.
First, we can identify any perfect square factors of 28. The largest perfect square factor of 28 is 4, which can be written as 2².
Using this knowledge, we can rewrite √28 as √(2² * 7).
Next, we can simplify the square root by taking the square root of the perfect square factor outside the root sign.
Taking the square root of 2² gives us 2.
Therefore, √28 simplifies to 2√7 in simplest radical form.
To express √28 in simplest radical form, we need to find the largest perfect square that can be factored out from 28. In this case, we can factor out 4, since 4 is a perfect square.
√28 = √(4 * 7)
Next, we can simplify the square root of 4 to its whole number value:
√(4 * 7) = 2√7
Therefore, √28 in simplest radical form is 2√7.
