deftype.l a,b,c,d
pow(a,4) +pow(b,4) +pow(c,4) = pow(d,4)

i run on my Pentium 155mhz, ahah

can find a,b,c,d

Does this code have any sense?

ahh,

Code: Select all

deftype.l a,b,c,d 
for a=1 to 255
for b=1 to 255
for c=1 to 255
for d=1 to 255
 if  pow(a,4) +pow(b,4) +pow(c,4) = pow(d,4) 
   debug a
   debug b
   debug c
   debug d
 endif
next d
next c
next b
next a

This will never be true, will it?!?

There is an infinite number of solutions

0^4 + 0^4 + 0^4 + 0^4 = 0^4

1^4 + 0^4 + 0^4 + 0^4 = 1^4

. . .

0^4 + 0^4 + 0^4 + n^4 = n^4

yes, but the other variable are never zero..

For the original question my solutions would work, but not so for the loops above, that's true

wow, but all number a,b,c,d greater zero!
