FAQ

How do exponents work?

aⁿ means multiply a by itself n times. 2⁴ = 2×2×2×2 = 16.

What about negative exponents?

a⁻ⁿ = 1/aⁿ. So 2⁻³ = 1/8 = 0.125.

What about fractional exponents?

a^(m/n) = ⁿ√(aᵐ). So 8^(2/3) = ³√64 = 4.

What is e^x?

e ≈ 2.718 is Euler's number. e^x is the natural exponential, inverse of ln(x).
