Theorem ostth2lem1 26671

Description: Lemma for ostth2 26690, although it is just a simple statement about exponentials which does not involve any specifics of ostth2 26690. If a power is upper bounded by a linear term, the exponent must be less than one. Or in big-O notation, 𝑛 ∈ 𝑜(𝐴↑𝑛) for any 1 < 𝐴. (Contributed by Mario Carneiro, 10-Sep-2014.)

**Hypotheses**
Ref	Expression
ostth2lem1.1	⊢ (𝜑 → 𝐴 ∈ ℝ)
ostth2lem1.2	⊢ (𝜑 → 𝐵 ∈ ℝ)
ostth2lem1.3	⊢ ((𝜑 ∧ 𝑛 ∈ ℕ) → (𝐴↑𝑛) ≤ (𝑛 · 𝐵))

**Assertion**
Ref	Expression
ostth2lem1	⊢ (𝜑 → 𝐴 ≤ 1)

Distinct variable groups: 𝐴,𝑛 𝐵,𝑛 𝜑,𝑛

Proof of Theorem ostth2lem1 Dummy variable 𝑘 is distinct from all other variables.
