Question

(1+1supra2) × (1-1supra3) × (1+1supra4) ×(1-1supra5) repede va rog​

Answer 1

Mai intai calculezi ce e in paranteza si il aplifici pe 1 cu acelasi numar ca langa cel de langa el

(2/2+1/2)*(3/3-1/3)*(4/4+1/4)*(5/5-1/5) = 3/2*2/3*5/4*4/5= 6/6*20/20 = 1*1 = 1

Answer 2

Răspuns:

(1 + 1/2) × (1 - 1/3) × (1 + 1/4) × (1 - 1/5) = 3/2 × 2/3 × 5/4 × 4/5 = 5/4 × 4/5 = 1
