Answer 1

các bạn giải hộ mình nhé

Answer 2

\(\frac{4\times5\times6\times7}{5\times6\times7\times8}+\frac{3}{2}\)

= \(\frac{4}{8}+\frac{3}{2}\)

= \(\frac{1}{2}+\frac{3}{2}=\frac{4}{2}=2\)

Answer 3

\(\frac{4\times5\times6\times7}{5\times6\times7\times8}+\frac{3}{2}\)

\(=\frac{4}{8}+\frac{3}{2}=\frac{1}{2}+\frac{3}{2}\)

\(=\frac{4}{2}=2\)
