So sánh A và B
a) A = \(\frac{10^7+5}{10^7-8}\) va B = \(\frac{10^8+6}{10^8-7}\)
b) A = \(\frac{n}{n+1}\) va B = \(\frac{n+1}{n+3}\) ( voi \(n\in N\))
c) A = \(\frac{n}{n+3}\) va B = \(\frac{n-1}{n+4}\) ( voi \(n\in N,\)\(n\ne0\) )
d) A = \(\frac{n}{2n+1}\) va B = \(\frac{3n+1}{6n+3}\) ( voi \(n\in N\))
