Question

c) fractia 17 la puterea n+2 -5*17 la puterea n+1 +17 la puterea n supra 3*19 la puterea n+1-90*19 la puterea n+19 la puterea n+2 se simplifica prin 41.
va rog :^ dau ce vrei când se poate​

Answer 1

Răspuns:

[17^n(17²-5×17+1)]/[19^n(3×19-90+19²)]=

(17/19)^n(289-85+1)/(57-90+361)=

(17/19)^n205/328=(17/19)^n(5×41/8×41)=

=(17/19)^n×5/8
