Work out laws of indices instantly with clear inputs, formula shown and shareable results.
Beyond the three basic laws, powers distribute over multiplication and division of bases, negative exponents give reciprocals, and a unit-fraction exponent is a root.
Distributing over a product
(bc)ᵐ = bᵐ · cᵐ
Negative exponent
b⁻ᵐ = 1 / bᵐ
Fractional exponent
b^(1/m) = ᵐ√b
(6)⁴ = 1296, (1.5)⁴ = 5.0625, 3⁻⁴ = 1/81 ≈ 0.0123457 and ⁴√3 ≈ 1.3160740.
No. Powers distribute over multiplication, never over addition — that is one of the most common algebra mistakes.
