Le guide ci-dessous n'est pas encore disponible en français et s'affiche en anglais. Le calculateur lui-même est entièrement traduit.
Comment utiliser ce calculateur
- Enter the base b.
- Enter the exponent n. Use 0.5 for a square root or 1/3 ≈ 0.333… for cube roots. For exact roots, use the scientific calculator with (1/3).
- Read bⁿ and its reciprocal b⁻ⁿ.
Formule
Exponent rules let you combine and simplify powers.
bⁿ = b × b × … × b (n times)
b⁻ⁿ = 1 / bⁿ
b^(1/n) = ⁿ√b
bᵐ × bⁿ = b^(m+n); (bᵐ)ⁿ = b^(mn); b⁰ = 1
Examples
- 2¹⁰ = 1,024.
- 10⁻³ = 0.001.
- 16^0.5 = 4; 2^0.5 ≈ 1.41421356237310.
Questions fréquentes
What is 0⁰?
In most contexts, including this calculator, 0⁰ is defined as 1.
Why can't I raise a negative number to 0.5?
The square root of a negative number isn't a real number. Odd roots such as (−8)^(1/3) = −2 are allowed.
How are huge results shown?
Results beyond 10²¹ appear in scientific notation, for example 1e+25.
