itensor and vector norm (?)



I start using Maxima 2 day's ago, so I'm having one maybe trival difficult.

For my Math project one of the tasks is to caluculate vector 1norm, 2norm, and infinity norm in Maxima, and vectors are:

X=(1,-3), Y=(1,8,-5),  Z=(3,-5,0,-9)

So any kind of help or suggestion would help a lot
