Exponent Calculator

Calculate powers, roots, squares, and cubes. From simple squaring to nth roots, this is your complete exponent toolkit — the E in GEMS.

Powers and Exponents Explained

An exponent tells you how many times to multiply a number (the base) by itself. For example, 2⁴ = 2 × 2 × 2 × 2 = 16.

The E in GEMS

The E in GEMS stands for Exponent — a nod to the exponential growth that underlies compound interest, population dynamics, computer science, and the universe itself. Every calculation starts with gems. ✦
