Calculate powers, negative exponents, fractional exponents, exponent products and quotients, and scientific notation with this free exponent calculator.
Power:
an means multiply the base by itself n times
Product rule:
am × an = am+n
Quotient rule:
am ÷ an = am−n
Scientific notation:
Move the decimal and count the places as a power of 10
Exponents are used in algebra, science, engineering, finance, and computing to represent repeated multiplication and very large or very small values.
They make it easier to work with powers, roots, growth, decay, and scientific notation.
Your result shows the power, rule result, or scientific notation result based on the mode selected. It also includes supporting values like exponent form, decimal form, and simplified rule output.
These extra values make it easier to check your work for algebra, science, engineering, or everyday calculations involving powers of numbers.
A negative exponent means take the reciprocal of the base raised to the positive exponent.
A fractional exponent represents a root and a power, such as x1/2 meaning the square root of x.
Add the exponents and keep the same base.
Scientific notation writes a number as a value between 1 and 10 multiplied by a power of 10.
