<p><span style="font-weight: bold; color: #0000ff;">Primer calculo el m.c.m dels índex #i i #j que és #m. Aquest és l'índex comú.</span></p> <p><span style="font-weight: bold; color: #0000ff;">A la primera arrel, he multiplicat l´index per #m1. Haig d'elevar el radicand #a1 a #m1<br /></span></p> <p><span style="font-weight: bold; color: #000080;"><span style="font-weight: bold; color: #0000ff;">A la segon arrel, he multiplicat l´index per #m2. Haig d'elevar el radicand #a2 a #m2</span><br /></span></p>
