Question

Stie cineva cum ajung la raspunsul acela va rog

Answer 1

Răspuns:

adevarat

Explicație pas cu pas:

1+0,1=1,1

1,1^(-3) =1/1,1³

(1-1/1,1³)*10=(1-0,7513148,..)*10≅0,2486852*10=2,486 ...etc

Adevarat

Answer 2

(1+0,1)⁻³=1/(1+0,1)³=1/(1,1)³=1/1,331=0,751

1-(1+0,1)⁻³=1-0,751=0,2486

1-(1+0,1)⁻³/0,1=0,2486/0,1=0,2486*10/1=2,486

A₁=A*1-(1+0,1)⁻³/0,1=2,486A
