An online exponent calculator that helps you to calculate the value of any positive or negative integer raised to any power. Also, this exponential calculator shows the results of the fraction power of any number. This useful content will cover all the related topics, how to calculate it manually and much more interesting data. But starts with some basics!

You can also use our online scientific notation calculator that allows you to add, subtract, multiply or divide any numbers in scientific notation.

What is an Exponent?

In Mathematics, it indicates how many copies of a number multiply together. For example; 74 , 7 is base and 4 is the exponent. In this example 4 copies of 7 are multiplied together to give 2401 as 7*7*7*7.

It is very easy to do the calculations with small values but for large & decimal bases or for the negative or decimal, large powers, use our fraction exponent calculator.

Basic Rules:

There are some basic rules for the exponentiation:

Product rule:

When multiplying a base term by two different exponents, then the resultant of both the powers is the power of base. E;g

\(a^m.a^n = a^{m+n}\)

Quotient Rule:

When dividing a base term by two different exponents, then the difference of both the powers is the power of base. E;g

\(a^m/a^n = a^{m-n}\)

Zero Rule:

The exponent of any number will be equal to 1. E;g

b0 = 1

Where b is any integer (positive or negative).

Also, you can try our online log and antilog calculator which is the inverse of the exponent function.

How to Calculate Exponents for Any Integer (Step-by-Step):

The calculations for power become easy with this power calculator, which helps to do the calculations for all the integers (negative, positive, fractions). Ahead to manual example:


Find 3 to the power 7?


The formula is:

\((x)^n = x*x*x*x*……..n\)

Here, x is 3 & n is 7. So,

\((3)^7= 3*3*3*3*3*3*3\)

\((3)^7= 2187\)

Further, if you have negative or fractional bases or exponents, then give a try to our online negative exponent calculator that helps you to determine the speedy results of negative or fractional inputs.
