Introduction
In literature quite a
large number of references are available for Fermat’s Last Theorem and Beal
conjecture [1]{2}{3}. The Pythagoras
theorem, FLT and Beal conjecture are different form of one and the same
multi-power relation under different condition. The most general form of three
member multi-power relation is xp + yq
= zr , where
both the base numbers (x,y,z) and the exponents (p,q,r) are all supposed to be
whole integers. Under different conditions, it gives Pythagorean relation (p =
q = r = 2), Fermat last theorem (p = q = r = n and n > 2) and Beal
conjecture (p,q,r are not equal, at least
one is different and p = q = r ≠ 2).
When x,y,z,p,q and r
are positive integers with p,q,r are greater than 2, then x,y,z will invariably
have a common prime factor, when the exponent of one or two base numbers is 2, the common prime
factor is not to be a necessary condition and when the exponents of all the
base numbers are equal, the common prime factor present can be cancelled out
and reduces ultimately to an irreducible form of the relation. In this paper a
simple proof for FLT and Beal conjecture is derived from the realistic
Pythagoras theorem.
1.FLT
in Five Steps
Step.1,Consider any
known Pythagorean triples (a,b,c) satisfying a2 + b2 = c2 , where a,b and c are all whole integers.
Dividing by a2 throughout
gives reduced Pythagorean relation as 1 + (b/a)2 = (c/a)2
Step,2 Let us suppose
an unknown three member like power relation
xp + yp = zp,
where x,y and z may or may not be
whole integers,
Step 3. Multiplying
throughout the reduced Pythagorean relation by xp gives
xp + xp (b/a)2
= xp (c/a)2
Step 4. Comparing term
by term with the unknown relation yp
= xp (b/a)2
and xp (b/a)2 + k
= (xα)p and zp = xp (c/a)2 and xp (c/a)2
+ k = (xβ)p where α and β are assumed to be whole integers
and k will be zero when (b/a)2 = αp
and (c/a)2 = βp if not k may have some positive or negative value
Step 5. Substituting
the derived values for (b/a)2 and
(c/a)2 in the reduced Pythagorean relation 1 + αp = βp . No integer or fractional
values of α and β will satisfy this relation for all values of p except p = 2.

Beal conjecture in Five steps
2
Step.1 Consider any
known Pythagorean triples (a,b,c) satisfying a2 + b2 = c2 , where a,b and c are all whole integers.
Dividing by a2 throughout
gives reduced Pythagorean relation as 1
+ (b/a)2 = (c/a)2
Step 2. Let us suppose
an unknown three member unlike power relation
xp + yq = zr where x,y,z,p,q and r are supposed to
be whole integers.
Step 3. Multiplying
throughout the reduced Pythagorean relation by xp gives
xp + xp (b/a)2
= xp (c/a)2
Step 4.Comparing term
by term with the unknown relation, yq = xp (b/a)2 = (xα)p
and zr = xp (c/a)2 = xp+k where α , β and k are all assumed to be
whole integers.
Step 5. Substituting
the derived values for (b/a)2 and
(c/a)2 in the reduced Pythagorean relation 1 + αp = xk. . Few possible solutions and
the corresponding multi-power relations are 1 + 23 = 32 gives 33 + 63 = 35 , 1+ 7 = 23
gives 73 + 74 = 143 and few general solutions are 1 + (2n – 1} = 2n gives (2n - 1)n
+ ( 2n -1)n+1 = [2(2n -1)]n and 1 + nm = (nm + 1) gives ( nm + 1)m
+ [n(nm +1)]m = (nm
+ 1)m+1.
III.
Conclusion:
The proof of FLT and
Beal conjecture in five steps shows that three member equal power relation is
not possible with all the base numbers are integers for all exponents greater
than 2 since 1 + αn ≠ βn
.However such relations are possible when exponents of the base numbers are
allowed to be different since 1 + αn = βm.When it is multiplied with a
common multiplier (βn) which becomes the common prime factor in Beal
conjecture we get a multi-power relation βn + (αβ)n = βm+n, while the common factor αm
gives αm + α m+n = (αβ)m .
