Add to square root 8+ square root 28+2 square root eight

To simplify the expression, we can combine like terms by adding square root 8, square root 28, and 2 times square root 8.

Square root 8 can be simplified as 2 times square root 2 because 2 multiplied by 2 gives 4, which is a perfect square.

Square root 28 can be simplified as 2 times square root 7 because there are no perfect squares that can be extracted from 28.

So, the expression becomes: 2 times square root 2 + 2 times square root 7 + 2 times square root 8.

Since all three terms have a coefficient of 2, we can factor out the 2: 2 (square root 2 + square root 7 + square root 8).
