Interactive FAQ

What is the difference between a power and an exponent?

The exponent is the number of times the base is multiplied by itself, while the power is the result of this multiplication.

Can I use this calculator for negative exponents?

Yes, our calculator supports negative exponents. The result will be a fraction with the base as the numerator and 10 raised to the absolute value of the exponent as the denominator.
