Question

Do sánh A = 10^8+2/10^8-1 và B= 10^8/-3

Answer 1

\(A=\frac{10^8-1+3}{10^8-1}=1+\frac{3}{10^8-1}\)

\(B=\frac{10^8-3+3}{10^8-3}=1+\frac{3}{10^8-3}\)

Vì \(\frac{3}{10^8-3}>\frac{3}{10^8-1}\) nên B>A

Answer 3

A = 10 ^ 8 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 +2/10^8 = 2/10 x 2/10 x 2/10 x 2/10 x 2/10 x 2/10 x 2/10 x 2/10 - 1 

B = 10 ^ 8 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 - 3 

 A = 100000000 + 1/390625 =100000000 - 1 = 9999999

B = 100000000 - 3 = 9999997

So sánh : 9999997 < 9999999

cho nên A lớn hơn
