Exponent Calculator is a free online tool that helps to find the value of an exponentiated expression. Repeated multiplication of the same number can be expressed in the form of an exponential expression.
What is an Exponent Calculator?
Exponent Calculator helps to compute the value for an exponential expression. Such an expression comprises two parts - the base and the power (exponent). Exponents can be both negative and positive. To use the exponent calculator, enter the values in the input boxes.
Note: Enter positive base values up to 2 digits and positive exponent values up to 10 digits

How Does Exponent Calculator Work?
An exponent is used to represent the number of times a number is multiplied by itself. Suppose we have a base denoted by x and its corresponding power given by n. This is represented as xn. This implies that the base x is being multiplied n times by itself. Exponents are very useful in representing very big or very small numbers. If we have a negative exponent, it signifies that the reciprocal of the base is being multiplied repeatedly. This is given by x-n. It indicates that 1/x is being multiplied n times. We can also have fractional exponents. Powers and roots together are represented by such types of exponents. Suppose we have an exponent represented as x1/2. This notation shows that we have to take the square root of the number x. Cube roots can also be represented using a similar notation. Another type of exponent is the decimal exponent. Such an exponent is expressed in the form of decimals. To evaluate such exponents the decimal needs to be converted to a fraction before proceeding further.
Solved Examples on Exponents:
Example 1: Find the exponential value for 104 and verify it using the exponent calculator.
Base = 10
Exponent = 4
104= 10 × 10 × 10 × 10 = 10,000
Example 2: Find the exponential value for 490.5 and verify it using the exponent calculator.
Base = 49
Exponent = 0.5. This can also be denoted as 1/2.
Thus, we have to find the square root of 49.
490.5 = 491/2 = 7.
Now, try the exponent calculator to find the value of the following exponents.
