JavaScript Math pow() Method
The Math. pow() method is used to power a number i.e., the value of the number raised to some exponent. Since Math.pow() is a static method of Math, it is always used as Math.pow() and not as a method of an object created in Math class.
Syntax:
Math.pow(base, exponent)Parameters:
- base: It is the base number that is to be raised.
- exponent: It is the value used to raise the base.
Return Value:
The Math.pow() method returns a number representing the given base raised to the power of the given exponent.
Example 1: In this example, we will use Math.pow() method.
console.log(Math.pow(3, 4));
Output
81
More codes for the above method are as follows:
Example 2: When both base and exponent are passed as positive numbers in parameters:
console.log(Math.pow(9, 3));
Output
729
Example 3: When the base value is negative and the exponent is positive:
console.log(Math.pow(-9, 3));
Output
-729
Example 4: When the base value is positive and the exponent is negative:
console.log(Math.pow(9, -3));
Output
0.0013717421124828533
Example 5: When the base value is negative and the exponent has decimal point: It returns NaN.
console.log(Math.pow(-9, 0.5));
Output
NaN

JavaScript Math.pow() Method – FAQs
What is the Math.pow() method in JavaScript?
The Math.pow() method returns the base raised to the power of the exponent, which is equivalent to base^exponent.
Can Math.pow() handle negative exponents?
Yes, Math.pow() can handle negative exponents, resulting in a fractional value. For example, Math.pow(2, -3) returns 0.125.
How does Math.pow() handle non-integer exponents?
Math.pow() can handle non-integer exponents, including fractional exponents. For example, Math.pow(9, 0.5) returns 3, which is the square root of 9.
What are some common use cases for Math.pow()?
Common use cases for Math.pow() include calculating powers and roots in mathematical computations, such as squaring numbers, finding cube roots, and more complex mathematical formulas that involve exponentiation.
What is the return type of Math.pow()?
The
Math.pow()method returns a number that is the result of raising the base to the power of the exponent. If either argument is not a number, the return value will beNaN.
