The exponent calculator determines that how many times a number (the base) is multiplied by itself. It has simple interface, just put the base and its exponents to calculate the exponent operation of large base integers and real numbers, including expressions that use the irrational number e as a bases.
In Mathematics, exponent mean the power. It indicates how many copies of a number multiply together. It’s written as a small raised number to the right of the base.
For Example:
In this example, 4 copies of 7 are multiplied together to give 2401 as 7*7*7*7.
When multiplying a positive base by two different exponents, then the resultant is the exponents of bases.
\(a^m.a^n = a^{m+n}\)
When dividing a positive or negative bases by two different exponents, then the difference of both the exponents is the power of bases.
\( {\frac{a^m}{a^n}} = a^{m-n}\)
The exponents of any number will be equal to 1.
\( b^0 = 1 \)
Where b is a base (positive or negative)
When a given bases having the power of its exponents, then both are multiplied together to get the single power.
\(({a^m})^{n} = {a}^{mn}\)
When the product of two integers having the power, then both the integers have the same power but separately.
\((ab)^x = a^x*b^x\)
When the power of the some integer is the negative number, then it will be equal to the reciprocal of the number. While the rules for fractional exponents with negative bases are the same.
\(a^-x = {\frac{1}{a^x}}\)
Find 3 raised to 7? where, 3 is a base and 7 is a exponent.
Solution:
The formula for non-negative is:
\((x)^n = x*x*x*x*……..n\)
Here, x is 3 & n is 7. So,
\((3)^7= 3*3*3*3*3*3*3\)
\((3)^7= 2187\)
A fractional exponent, like a²/³ is where the exponent is a fraction. It can be written as a root as well, like ³√a.
Now, calculating exponents for both negative as well as positive integers become very easy with the exponent calculator. Look at the table below for some common values of integers:
