Exponents Calculator
Step-by-Step: 3 to the power of 2
Multiply the base 3 by itself 2 times:
3 × 3 = 9
Same as 3 Squared
Since the exponent is 2, this calculation is the same as 3 squared:
32 = 9

Notation and Properties of Exponents
The expression bn is read as "b to the power of n", where b is the base and n is the exponent. Several common-language equivalents:
- b2 = "b squared" (the area of a square with side b)
- b3 = "b cubed" (the volume of a cube with edge b)
- bn = "b to the nth" (general usage)
Key rules
- Zero Rule: b0 = 1 for any b ≠ 0
- One Rule: 1n = 1 for any n
- Negative exponent: b−n = 1 / bn
- Fractional exponent: b1/n = n√b (e.g. b0.5 = √b)
- Product rule: bm × bn = bm+n
- Power rule: (bm)n = bm·n
Constants supported
This calculator accepts the mathematical constants pi (π ≈ 3.14159) and e (Euler's number ≈ 2.71828), with optional leading minus (-pi, -e) for negative variants.
