Explicație pas cu pas:
prima paranteza de sub radical:
1/1-1/2+1/2-1/3+1/3-1/4+.........1/36-1/37=1-1/37=36/37
a doua paranteza:
1/37-1/38+1/38-1/39+1/39-1/40+......1/73-1/74=1/37-1/74
scaderea parantezelor:
36/37 - 1/37+1/74=35/37 + 1/74=(70+1)/74
inmultirea finala:
(74/71)ꞏ(71/74)=1
raspuns final x=1
