what does "xbase to" mean?
The number of the positive integral of 2x + 3y+ 4z+ 5m= 25 , is.
you mean positive integers x,y,z,m such that
2x + 3y+ 4z+ 5m= 25
?? There can't be that many, so start listing them, since
m<4
2x+3y+4z + 5*3 = 25 has no solutions
2*1 + 3*3 + 4*1 + 10 = 25
There are only a couple of other possibilities. I think you will find that m must be 2 or 4.
