Question

 

So sánh:

M=\(\frac{10^7+5}{10^7-8}\) và   N=\(\frac{10^8+6}{10^8-7}\)

Answer 1

\(M=\frac{10^7+5}{10^7-8}=\frac{10^7-8+13}{10^7-8}=1+\frac{13}{10^7-8}\)

\(N=\frac{10^8+6}{10^8-7}=\frac{10^8-7+13}{10^8-7}=1+\frac{13}{10^8-7}\)

Ta có \(10^8-7>10^7-8\) \(=>\frac{13}{10^8-7}< \frac{13}{10^7-8}\) \(=>M< N\)

Vậy M<N
