A-B=-x thi A<B.    Voi x>0

 Lam trac nghiem kieu nay la dc day. Hi

cậu có thể làm rõ hơn kkhông

A > B

làm thế nào cho nó gọn gọn xíu rồi ss nha

\(A=\dfrac{5\left(11.13-22.26\right)}{22.26-44.52}\)
\(=\dfrac{5\left(11.13-22.26\right)}{2\left(11.13-22.26\right)}\)
\(=\dfrac{5}{2}\)
\(B=\dfrac{138^2-690}{137^2-548}\)
\(=\dfrac{138^2-138.5}{137^2-137.4}\)
\(=\dfrac{138\left(138-5\right)}{137\left(137-4\right)}\)
\(=\dfrac{138.133}{137.133}\)
\(=\dfrac{138}{137}\)
Ta có:
\(\dfrac{5}{2}=\dfrac{685}{274}\)
\(\dfrac{138}{137}=\dfrac{276}{274}\)
Vì vậy mà \(A>B\)
#die

a>b

kick nhe

E=\(\frac{5.\left(11.13-22.26\right)}{22.26-44.52}\)=\(\frac{5.\left(143-572\right)}{572-2288}\)=\(\frac{5.143-5.572}{572-2288}\)=\(\frac{5}{4}\)=1,25

F=138²-\(\frac{690}{137^2}\)-548=19044-\(\frac{690}{18769}\)-548=19043,96324-548=18495,96324

vì 18495,96324>1,25 nên F>E

\(\frac{138\cdot138-690}{137\cdot137-548}\)=\(\frac{137+1\cdot137+1-548+142}{137\cdot137-548}\)=\(\frac{1+1+142}{1}\)=\(\frac{144}{1}\)=144

Giúp mình với
