√23
That IS the simplest radical form.
The square root of 28 or in this case the radical form of 28 will be 2 times radical 7. Since 28 is 4 times 7 and the square root of 4 is two.
radical 15 cannot be simplified.

The square root of six divided by the square root of two equals the square root of three.
That IS the simplest radical form.
The square root of 28 in simplified radical form is...2 * Square root of 7
You can't simplify it more in radical form
The square root of 125 in radical form is 5 x (square root of 5).
2i radical 5 * * * * * No. it is ± i*radical(25) which is ± 5i. Not sure why the answer is requireed in radical form.
The rules for "standard radical form" are that (a) there should be no perfect square within the radical sign; for example, square root of 12 is equal to square root of 4 x square root of 3 = 2 x square root of 3, and should be written as the latter; and (b) there should be no radical sign in the denominator. For example, if you have 1 / square root of 2, you multiply top and bottom by the square root of 2, to get a square root in the numerator, but none in the denominator.

The square root of 14 is already in its simplest radical form. The number itself is roughly 3.7416573867739413
