Proof: Simplify Product
Let's prove the following theorem:
(a ⋅ (1 / b)) ⋅ (c ⋅ (1 / d)) = (a / b) ⋅ (c / d)
Proof:
# | Claim | Reason |
---|---|---|
1 | a ⋅ (1 / b) = a / b | a ⋅ (1 / b) = a / b |
2 | c ⋅ (1 / d) = c / d | c ⋅ (1 / d) = c / d |
3 | (a ⋅ (1 / b)) ⋅ (c ⋅ (1 / d)) = (a / b) ⋅ (c / d) | if a ⋅ (1 / b) = a / b and c ⋅ (1 / d) = c / d, then (a ⋅ (1 / b)) ⋅ (c ⋅ (1 / d)) = (a / b) ⋅ (c / d) |
