= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
3. 4. เมื่อ a  0
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
5. เมื่อ a และ b  0 6. เมื่อ a, b และ c  0
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
= _________________________ = _________________________
