N-1
X=SIGMA A[i]*B^i = A[m]*B^m + A[m+1]*B^m+1 +...+ A[n-1]*B^n-1 + A[n]*B^n
i=M
N is upper bound, M is lower bound.
My formula is X=N(B^(P-1)) + N(B^(P-1))
Using MY variables I plug this into the the SUM like this:
P-1
X=SIGMA N[i]*B^i
i=0
4711 = 1*25^0 + 1*25^1 + 7*25^2 + 4*25^3
Any number to the power 1 is itself.
Any nonzero number to the power 0 is 1
Exponentiation is a^n=a x ... x a
