Add 2 square root 8 + square root 28 + 2 square root 8

Answer 1

To simplify 2 square root 8 + square root 28 + 2 square root 8, we can combine like terms.

First, simplify the square roots:
√8 = √(4 * 2) = 2√2
√28 = √(4 * 7) = 2√7

Now, the expression becomes:
2√2 + 2√7 + 2√2

Combining like terms, we have:
(2√2 + 2√2) + 2√7
= 4√2 + 2√7

Therefore, 2 square root 8 + square root 28 + 2 square root 8 simplifies to 4√2 + 2√7.
