Cho biết 153²=23 409. Hãy tính √23 409
So sanh: A=196/197+197/198 va B=196+197/197+198
Ta có:
B=196+197/197+198<196+197/198=196/198+197/198<A
=> B<A
Vậy A>B

cho A= (196/197)+(197/198)
B=(196+197/197+198)
so sánh A và B

So sánh
A= 197/198 +198/197 và B= 197+198/198+197
197/198+198/197=78013/39006
197+198/198+197=1
Vì78013/39006>1 nên A>B

Cho A=196/197+197/198 và B= 196+197/197+198. So sánh A và B.
\(B=\frac{196+197}{197+198}=\frac{196}{197+198}+\frac{197}{197+198}\)
\(\frac{196}{197}>\frac{196}{197+198};\frac{197}{198}>\frac{197}{197+198}\)
=>A>B
