Proof: Add 1 to Exponent
Let's prove the following theorem:
x(m + 1) = (xm) ⋅ x
Proof:
# | Claim | Reason |
---|---|---|
1 | x(m + 1) = (xm) ⋅ (x1) | x(m + 1) = (xm) ⋅ (x1) |
2 | x1 = x | x1 = x |
3 | (xm) ⋅ (x1) = (xm) ⋅ x | if x1 = x, then (xm) ⋅ (x1) = (xm) ⋅ x |
4 | x(m + 1) = (xm) ⋅ x | if x(m + 1) = (xm) ⋅ (x1) and (xm) ⋅ (x1) = (xm) ⋅ x, then x(m + 1) = (xm) ⋅ x |
