Proof step 9 from proof pot-root-est (previous step)

2 * i = j * j + j0, j = sqrt(2 * i), 2 * i < (j + 1) ^ 2, 0 < i, (2 * i) ^ j < ((j + 1) ^ 2) ^ j, 0 ≤ i, 4 ^ (i / 3) ≤ (2 * i) ^ sqrt(2 * i), 1024 ≤ i, j0 ≤ 2 * j, 0 ≤ j, 0 ≤ j0 ⊦

Proof step 10:
2 * i = j * j + j0, j = sqrt(2 * i), (2 * i) ^ j < ((j + 1) ^ 2) ^ j, 0 < i, 2 * i < (j + 1) ^ 2, 0 ≤ j0, 0 ≤ j, j0 ≤ 2 * j, 1024 ≤ i, 4 ^ (i / 3) ≤ (2 * i) ^ sqrt(2 * i), 0 ≤ i, j ^ 2 ≤ 2 * i ⊦
Proof step 49:
2 * i = j * j + j0, j = sqrt(2 * i), (2 * i) ^ j < ((j + 1) ^ 2) ^ j, 0 < i, 2 * i < (j + 1) ^ 2, 0 ≤ j0, 0 ≤ j, j0 ≤ 2 * j, 1024 ≤ i, 4 ^ (i / 3) ≤ (2 * i) ^ sqrt(2 * i), 0 ≤ i ⊦ j ^ 2 ≤ 2 * i
