To simplify the given expression, we combine like terms:
√8 - 2√7 - √8 + 2√7(√8 - √8) + (-2√7 + 2√7)0 + 00
Therefore, the simplified expression is 0.
To simplify the given expression, we combine like terms:
√8 - 2√7 - √8 + 2√7
(√8 - √8) + (-2√7 + 2√7)
0 + 0
0
Therefore, the simplified expression is 0.
