Question

3 la puterea 2014+4 la puterea 2014<5 la puterea 2014 rezolvare

Answer 1

3la2014+4la2014<5la2014
impartim la 5la2014.deci (3la2014)/(5la2014)+(4la2014)/(5la2014)<1
(3/5)la2014+(4/5)la 2014<1
(0.6)la2014+(0.8)la2014<1
dar(0.6)la2014=(0.6)(0.6)la1007=(0.36)la1007
(0.8)la2014=(0.8)(0.8)la1007=(0.64)la1007
cum 0.64+0.36=1 rezulta ca daca mai ridicam la putere:
(0.64)la1007<0.64
(0.36)la1007<0.36.deci
(0.64)la1007+(0.64)la1007<0.64+0.36=1
