Exponent Calculator to Calculate
Base Raised to nth Power

[ Skip to Calculator ] Calcy pointing down

Exponent calculator that will calculate the product of an exponential expression (xy, or x raised to the power of y).

This free online Exponents Calculator will calculate the answer of a base number raised to nth power, including exponential expressions having negative bases and/or exponents.

Note that if you're ever looking to save some time when finding the square root of a number (2√x instead of x2), be sure to check out my online square root calculator.

Exponent Definition

An exponent is the small number located in the upper, right-hand position of an exponential expression (baseexponent), which indicates the power to which the base of the expression is raised.

The following exponential expression shows how the exponent is used in raising the base:

43 = 4 x 4 x 4 = 64

4 x 4 = 16
4 x 16 = 64

Negative Exponents

An exponential expression containing a negative exponent can be translated as follows:

4-3 =
1
43
=
1
64
= 0.015625

Negative Bases in Exponential Expressions

One thing to be aware of when working with exponential expressions that have negative signs next to their bases is that a negative sign that is not in parenthesis is different from a negative base that is enclosed by a parenthesis.

(-4)4 = -4 x -4 x -4 x -4 = 256

-44 = -1 x 4 x 4 x 4 x 4 = -256

With that, let's use the Exponent Calculator to calculate the result of a number raised to a given power.

Base of exponential expression: Enter the base number of the exponential expression. For example, in the expression 24, the number two would be the base. If you are entering a negative sign you will need to select whether or not the negative sign and base are in parenthesis. (-4)2 = 16 whereas -42 = -16 (additive inverse of 42).

Exponent (base raised to this power): Enter the positive or negative integer of the exponential expression. For example, in the expression 24, the number four would be the exponent.

Result of base raised to entered power: This is the entered base number raised to the entered exponent.
