Thanks for replying, but i tried to do the matrix by hand and the last row give me 0 0 0 0/ -744a - 8580b - 91d - 1374e and i concluded that if this matrix should give me a unique solution then -744a - 8580 b - 91d - 1374e = 0 but the real question giving by the teacher is to find something like this and the i could discribe that the subset of E (for exemple ): (Discription): E {(a,b,c,d,e)∈R5∣ -744a -8580b - 91d - 1374e = 0} a plan resembles to ax +by+cz = d but this (ax+by+cz+dw+ev=0) i don't know If you can help me please)

In québec, L means: l'enseble des combinaisons linéaires wich i think it means the enseble of the linear combinations For the second question i made the correction it is the secon matix A i give in my post (it is not a diagonal matix)

Yes when it reached A^4 it stops. I mean even if you go higher it wont give you a different matrix but how could i write this down in maple for my teacher. Do i have just to show him and explain him this.
