2 * Square root of 7
2√7
2√7
In radical form, it is √256 But 256 = 28 so √256 = √(28) = 24 = 16
It is a square number but not a natural square
First we have to factor the radicand into square factors (Hint: *The best squares* try 100, 25, 16, 9 and 4. If none of these work, then try other square factors.) 4 is a factor of 28 so we can rewrite √28 as √4x7 Since 4 is a square factor, we take the square root of 4 which is 2. We put the 2 in front of the radical symbol: 2√7 Now, the radicand is 7 which does does not have square factor. Therefore the simplified radical is 2√7 . this is read "2 times the square root of 7"
technically the square root of 28 is to hard to find because it would go on and on, so most math maticians say that the answer to the square root of 28 is the square root of 28.
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.

no, 28 has no whole square root; the square root of 49 is 7
irrational
28 square root of 6 is approximately 68.59. Plug 28 back to the root will be V4704.
There is no square root of 794 but there is a square root for 784. It is 28.
The square root of 28 minus the squared root of 7 =±2.64575131
5 square root 7 because 3 square root of 28 goes from 3 square root of 28 to 3 square root of 7 and 4 which then 4 condenses down to 2 and you add that to 3 then you get 5 square root of 7
