An exponent tells you how many times to multiply a number (the base) by itself. Two to the power of three means 2 times 2 times 2, which equals 8. Exponents provide a compact notation for repeated multiplication and appear throughout mathematics, science, finance (compound interest), and computing (binary and byte measurements).
Powers of 2 are fundamental in computing: 2^10 = 1,024 (approximately one kilobyte), 2^20 = 1,048,576 (approximately one megabyte), 2^30 = 1,073,741,824 (approximately one gigabyte). This is why storage and memory sizes are powers of 2.
Any number raised to the power of zero equals 1. Any number raised to the power of 1 equals itself. Any number raised to the power of -1 equals its reciprocal. A fractional exponent represents a root: x to the power of 1/2 is the square root of x, and x to the power of 1/3 is the cube root. Negative exponents produce fractions: 2 to the -3 equals 1 divided by 8.
