Question

So sánh \(A=\frac{10^8+2}{10^8+1};B=\frac{10^8}{10^8-3}\)

 

Answer 1

\(A=\frac{10^8+2}{10^8+1}=1+\frac{1}{10^8+1}

Answer 2

10^8+2>10^8

10^8+1<10^^8-3

Answer 3

\(10^8=a\)

\(A-B=\frac{a+2}{a+1}-\frac{a}{a-3}=\frac{\left(a+2\right)\left(a-3\right)-a\left(a+1\right)}{\left(a+1\right)\left(a-3\right)}=\frac{-2a-6}{\left(a+1\right)\left(a-3\right)}
