#5 Posted 0:06pm 21-03-09 Re: Algebra-1([p]3[/p]√5+√3+z)[p]6[/p] = [([p]3[/p]√5+(√3+z)][p]6[/p] t[ss]r+1[/ss] = [p]6[/p]C[ss]r[/ss] 5[p]6-r/3[/p](√3+z)[p]r[/p] [r<=6] t[ss]k+1[/ss] = [p]r[/p]C[ss]k[/ss]z[p]r-k[/p]3[p]k/2[/p] [k<=r] now tr+1 is ratioal if r=0,3,6.. and tk+1 is raional for k=0,2,4,6 so, r k 0 0 3 0,2 6 0,2,4,6. so 7 rational terms.

#8 Posted 0:18pm 21-03-09 Re: Algebra-1@dimension,...okie..it depends. @prophet sir, will u pls solve this one by multinomial.. i actually dunno it .. [2]
