LES INC\u00d2GNITES<\/strong><\/p>\n

La major part dels cops quan tenim inc\u00f2gnites ho expressem mitjan\u00e7ant la “x”. Ens podem preguntar: I quan es va introduir la “x”?
\nLa “x” neix de la paraula \u00e0rab “shei<\/span>” que s’utilitzava per representar una quantitat num\u00e8rica no coneguda.
\nEls escriptors\u00a0gregs<\/span>\u00a0que tradu\u00efen textos matem\u00e0tics \u00e0rabs, per simplicitat, la van traduir com a “xei<\/span>“, molt m\u00e9s f\u00e0cil de llegir a l’alfabet hel\u00b7l\u00e8nic. Amb el temps els c\u00e0lculs van guanyar complexitat i “xei<\/span>” es va anar simplificant fins a convertir-se en “x”.<\/p>\n
