How to use: Calculate powers/exponents (base raised to an exponent). Enter Base (number to be multiplied) and Exponent (number of times to multiply). Formula: base^exponent. Examples: 2³ = 2×2×2 = 8, 5² = 5×5 = 25, 10⁴ = 10,000. Special cases: x⁰ = 1 for any x, x¹ = x, negative exponents = 1/x^n (2⁻³ = 1/8 = 0.125). Applications: compound interest calculations, population growth models, scientific notation (6.02×10²³), area/volume scaling (double radius = 4× area), physics (energy = mc²). Exponential growth appears in finance, biology, and technology adoption. Essential for algebra, calculus, and scientific calculations.
