Question

So sánh

E=5.(11.13-22.26)/22.26-44.52 và F=138²-690/137²-548

Answer 1

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
