Frequently Asked Questions

What is an exponent?

An exponent (also called a power) indicates how many times a base number is multiplied by itself. For example, 2³ means 2 × 2 × 2 = 8. The notation aⁿ represents the base 'a' raised to the power 'n'.

What happens when the exponent is 0?

Any non-zero number raised to the power of 0 equals 1. For example, 5⁰ = 1 and 100⁰ = 1. The expression 0⁰ is mathematically indeterminate, though it is often treated as 1 in combinatorics and some other fields.

How do negative exponents work?

A negative exponent means you take the reciprocal of the base raised to the positive version of that exponent. For example, 2⁻³ = 1 / 2³ = 1 / 8 = 0.125. Negative exponents represent fractions rather than negative results.

Can I use decimal or fractional exponents?

Yes. Decimal exponents are fully supported — enter the decimal form of any fraction as the exponent. For example, an exponent of 0.5 is equivalent to a square root, so 9^0.5 = 3. An exponent of 0.333... is equivalent to a cube root.

What is the rule for multiplying exponents with the same base?

When multiplying two powers that share the same base, you add the exponents: aⁿ × aᵐ = a^(n+m). For example, 2² × 2⁴ = 2^(2+4) = 2⁶ = 64.

What is the rule for dividing exponents with the same base?

When dividing two powers that share the same base, you subtract the exponents: aⁿ ÷ aᵐ = a^(n−m). For example, 3⁵ ÷ 3² = 3^(5−2) = 3³ = 27.

Can the base be a negative number?

Yes, negative bases are supported. Keep in mind that a negative base raised to an even exponent yields a positive result, while a negative base raised to an odd exponent yields a negative result. For example, (−2)³ = −8, but (−2)⁴ = 16.

What is the difference between exponentiation and multiplication?

Multiplication is repeated addition (3 × 4 = 3 + 3 + 3 + 3), while exponentiation is repeated multiplication (3⁴ = 3 × 3 × 3 × 3 = 81). Exponentiation grows much faster than multiplication as numbers increase.
