Question

Ex 1)Calculati suma : S=0, 2+0, 4+0, 6+08
Ex2) calculati produsul:0, 1*0, 3*0, 5*0, 7*0, 9

Answer 1

S=0, 2+0, 4+0, 6+0,8=2(0.1+0.2+0.3+0.4)=2*0.4*0.5:5=0.4*0.5=2
asta cu formula lui gauss mai simplu le aduni si obtii 2


P=0, 1*0, 3*0, 5*0, 7*0, 9=0,00945

Answer 2

S=0, 2+0, 4+0, 6+0,8=2(0.1+0.2+0.3+0.4)=2*0.4*0.5:5=0.4*0.5=2
asta cu formula lui gauss mai simplu le aduni si obtii 2


P=0, 1*0, 3*0, 5*0, 7*0, 9=0,00945
