Proof step 3 from proof pot-nls (previous step)

i ^ j < i, 0 < j, 0 < i ⊦

User applied rule cut formula

And obtained the following new goals

Proof step 4:
0 < i, 0 < j, i ^ j < i, i ^ j < i ^ 1 ⊦

Rule argument

fma: i ^ j < i ^ 1

Additional information

Used simplifier rules: one: ⊦ i ^ 1 = i;% ⊦ i < j ↔ ¬ j ≤ i; (ss)% ⊦ i < j → (j ≤ i ↔ false); (as) Used formulas: i ^ j < i ^ 1
