Văn là món ăn tinh thần cho con người. Nó là một loại hình nghệ thuật đặc sắc không thể thiếu. Từ xa xưa, khi cn người còn chưa có chữ viết nhưng họ cũng đã biết sáng tác những câu ca dao để lưu truyền đến tận bây giờ. Văn thơ phong phú cũng như từ ngữ của người Việt. Tâm hồn cn người ta đk nuôi dưỡng bởi văn thơ, âm nhạc. Đứa trẻ nào ngày bé cx đk mẹ hát những câu hát ru đưa vào giấc ngủ. Vậy đó, những lời ru ấy có tác giả kh? Không hề, nó đk xuất phát từ những câu ca dao và tấm lòng người mẹ. Đến khi biết nói, biết cười,chúng ta cx bập bẹ những bài vè hay những bài ca dao ngắn do bà, do mẹ dạy. Khi đi học, ta lại đk bt rõ hơn về văn, thơ. Chúng ta biết làm những bài tập làm văn. Chúng ta đk thầy cô dạy dỗ, chỉ bảo để vt thế nào cho hay, cho đúng. Văn đâu đơn thuần chỉ là đk tạo nên bởi những cn chữ. Chúng đáng đk nâng niu và trân trọng hơn nhiều

\(\left(3\sqrt{7}\right)^2=63>28=\left(\sqrt{28}\right)^2\) hoặc \(3\sqrt{7}>2\sqrt{7}=\sqrt{28}\)

12 tháng 10 2021

C1: $\sqrt{28}=\sqrt{4.7}=2\sqrt 7$

Ta có: $3>2$

$\Leftrightarrow 3\sqrt 7>3\sqrt 7$ hay $3\sqrt 7>\sqrt{28}$

C2: $3\sqrt{7}=\sqrt{63}$

Ta có: $63>28$

$\Leftrightarrow\sqrt{63}>\sqrt{28}$ hay $3\sqrt 7>\sqrt{28}$
