  1. 1

    Multiply 2 by itself 10 times

    2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 1,024

How it works

  • A whole-number exponent means repeated multiplication: 2⁴ = 2 × 2 × 2 × 2 = 16.
  • A negative exponent means 1 divided by the positive power: 2⁻³ = 1 ÷ 2³ = 0.125.
  • A fractional exponent is a root: 8^(1/3) is the cube root of 8, and x^(p/q) is the qth root raised to the power p.
  • Any non-zero number to the power 0 equals 1.

Frequently asked questions

Why is a negative number to a decimal power undefined?

It would need an even root of a negative number, for example (−8)^0.5 = √−8, which has no real answer.

How are very large answers shown?

Answers of a quadrillion or more, or smaller than 0.000001, are shown in scientific notation, such as 1.2 × 10¹⁸.
