Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

exponent

The small raised number that says how many times to multiply a base by itself.

In $b^n$ , the exponent $n$ tells you how many times the base $b$ is multiplied by itself: $b^3 = b\cdot b\cdot b$ . Exponents extend to zero, negative, and fractional values via the rules $b^0=1$ , $b^{-n}=1/b^n$ , and $b^{1/n}=\sqrt[n]{b}$ .

Examples

$2^5 = 2\cdot2\cdot2\cdot2\cdot2=32$ ; the exponent is $5$ , the base is $2$ .
