Exponent Calculator

Raising to a power means multiplying a number by itself a set number of times: 2¹⁰ is ten 2s multiplied together, which is 1,024. Powers sit behind everything from compound interest to computer memory.

The exponent need not be a whole number. A negative exponent gives the reciprocal (2⁻³ = 1/8) and a fractional one gives a root (9^0.5 = √9 = 3). The calculator handles all of them.

How to calculate Exponents

1. Enter the base (a).
2. Enter the exponent (n); it can be negative or a decimal.
3. Read aⁿ, the n-th root and the scientific notation.

Exponents formula

• aⁿ = a × a × … × a (n times)
• a⁻ⁿ = 1 ÷ aⁿ
• a^(1/n) = ⁿ√a
• aᵐ × aⁿ = aᵐ⁺ⁿ

Exponents example

2¹⁰ = 1,024. Its reciprocal 2⁻¹⁰ = 0.0009765625, and the square root of 2 is 2^0.5 = 1.4142136.
